CHARACTERISTICS

Vista multifinestra di una struttura mista in c.a. e acciaio.The structural calculation package CDSWin (Computer Design of Structures) is a powerful calculation tool, which allows the analysis of any structure to be performed with totally 3-dimensional schematization, via the most sophisticated f.e.m. (Finite element method) techniques. The structural analysis can be performed both in an elastic regime, using the hypothesis of indefinitely linear constitutive links, both taking into account the effect of geometric non-linearity (P Delta effect)as well as in non linearity of the materials, due to elements that react only to traction or compression. The calculation gives the possibility of selecting between seismic static and dynamic analysis . Seismic analysis can also be performed in cases of structures that don=t have rigid planks (seismic node analysis). The structure can be constituted of metal members, concrete, wood, or other material (to be chosen by the user) bi-dimensional elements with slate-plate behavior in concrete, steel, wood, or other isotropic or ortotropic material (to be chosen by the user); it can also have restraints and geometry of any type. Struttura in c.a. per auditorium.Structures with brace, pitch roofs, inclined members, plates in elevation and in foundation (slabs), vertical or inclined separators, even perforated, with slate and/or slate-plate behavior, symmetrical axial, etc. The number of modes to be considered in the dynamic analysis, seism and the respective input directions, number of load conditions and the relative load combinations can be decided upon. The members that converge in the same node can have differentiated restraints (even elastic), making the recurring situations in the metallic carpentry easily schematized. The calculation program determines the characteristics of the actions and performs all the appraisals of the resistance (by flexure or press flexure, torsion and shear both to the allowable stresses as to the ultimate limit state of the operation or according to the specifications of the Eurocode 2 and 3), for the members in concrete, metallic members, those in wood and for bi-dimensional elements in concrete. Also, the package takes into account the shear strain of the members and the eventual presence of initial and final parts that are rigid. In particular, the offsetting provided in input for the positioning of the beams and columns are taken into account automatically by the calculation model: a precise correspondence between the graphic model and the structure of the static schema analyzed follows. Foundations can be inserted on more than one level (with Winkler beams, direct plinths and on piles, direct slabs and on piles), also evaluating the foundation - structure interaction. The input is constituted by a structural CAD that is appropriately studied and equipped with sophisticated direct pointing on video characteristics of the structural elements (nodes, members, separators, plates, slates, direct plinths or on pile, etc.), which allow a quick insertion of the structure and easy graphic control of the data. Particolare nodo colonna-plinto.The program was organized according to a modular structure, that in order to come closer to the different professional needs, allows each user to purchase only the modules that he/she is actually interested in, therefore saving a notable amount of money. Some of the characteristics of CDSWin that are worthy of being noted are the following: Graphic interface projected according to the Windows standard (multiple windows, toolbars, drop-down menu=s etc.) - multilevel UNDO REDO: with the possibility of restoring the previous situations at each command Rendering algorithms and hidden lines (photorealistic views with shadows) with an accurate representation of the permeations between structural elements.- animation procedure in rendering of the structure-. Possibility of capturing images from the video (for example : color maps and distortions) and importing them on the document to format them together with the images and text. WinCAD program powerful and flexible 3-dimensional CAD developed by STS. The CAD environment foresees various options; for the graphic elements: point, line, arch, circle, polyline, 3D face, blocks, outlines; For osnap modalities: center, end, perpendicular, intersection, middle, near, node, etc. CDSWin is the only structural program equipped with two input graphic modes studied in order to make data insertion in the topology of structure easier. So, next to the classic input of planks, we have particularly aimed for the definition of buildings in concrete, even on input mode studied for structures with complex geometries (for example: lattice, spatial reticular girders, etc.). It=s worthy to underline the fact that the two types of inputs mentioned above can be used contemporaneously for the definition of another structure that is mixed steel/concrete. You can define the part in concrete with the input for planks, and the remaining part in steel with spatial input. The following pages describe the two input modalities, separately:

 

INPUT FOR PLANKS

The input for planks is articulated in 14 phases:
1. Archives;
2. Base line;
3 Level;
4. Column;
5. Plinths.
6. Slab/Plate
7. Beam/Separator;
8 Separator perforation;
9. Node dimension;
10. Loads;
11. Restraints;
12. Floor generation;
13. Space generation;
14. Plant drawings;
Inserimento travi e pilastri .An architectural drawing can be imported in CDSWin in DXF format, in order to facilitate the input of the elements using specific snap functions (intersections, etc.), which CDSWin is equipped with. In this phase and in the following phases, copy, cancel, etc. are available, which allow the elements inserted to change interactively . Gestione dell'archivio delle sezioni in c.a..After the base lines, the level of the floor plan and the columns are defined for each plan. Once a reference line is set, the columns are Ainserted@ on it. The center of the column can be offset respect to the line in X and Y of any type of deviations and the entire column can also be eventually rotated around its own axis. The section of the column, as that of the beam can have any form, from rectangular, to T, to circular, or even polygonal. In the next calculation phase, all of these sections will be verified correctly with rigorous routines of verification of TENSO/PRESSO flexure straight or deviated. Plinths of foundations direct on piles can be inserted under the single columns, which will then be calculated and drawn in connection with the CDPWin program. For the solution of CDSWin static schema is generated automatically, which provides elastic restraints in correspondence to each plinth, correctly schematizing the interaction of foundation-structure. In the next phase, the beams are defined, both of the foundation as well as of the elevation. Inclined members on plan and vertical members can be inserted. Another peculiarity of the program consists of the possibility to offset the extremities of the beam respect to the base line of reference: this allows the management of particular situations that are frequently a use of the technical practice (as shown on the figure on the side). The bi-dimensional elements (shells) can also be defined, always in a graphical manner, which schematize recurring situations of walls of restraints from which columns come out of the first floor, shelves of brace, with or without perforations, etc.Gestione archivio plinti.Horizontal or inclined bi-dimensional elements can be defined with the slab/plate phases, which allow the characterization of sloping roofs, inclined with full slab, foundation slabs, etc. The combination of vertical, horizontal and inclined bi-dimensional elements also allows the analysis (and the relative verification and iron drawing) of particular structures, which can be for example: tanks, vaulted roof, dome-vault, etc. The bi-dimensional vertical elements schematize even elements in masonry. So, thanks to the interaction with the program CDMaWin, the structures in masonry or structures which contemporaneously have elements both in masonry, beam, columns and separators in concrete or iron can be resolved. The insertion of eventual perforations in the vertical separators is made particularly feasible from the apposite procedure of separator permeations, which is completely assisted by graphics. It is also possible to insert and/or modify the internal and external restraints (hinges, horizontal and vertical bi-pendium rules, trucks, etc). The node dimension procedure allows the modification of the single nodes, with automatic dragging of all the beams and columns corrected. This procedures obtains the vaults that have a complex form, starting from a horizontal plate, the relative mesh will be created automatically by the program. On the same dimension, you can define two or more different sismic planks (for example buildings and independent towers). Any input phase is accompanied with "zoom" and "pan", and of dynamic selection of the point of view. The loads foreseen in CDSWin largely cover all of the points of interest in the technical practice. In fact, the following types are defined:
1. Floors
2. Balconies
3. Perimeter walls
4. Explicit
5. Special floors
6. Shell thrust
7. Concentrates
8. Staircase

Inserimento carico tipo scala.The load topologies foreseen and the input modality studied, Aguide@ the user to an easy analysis of the loads that rest on each structural element. Inputting the loads is easy: the information requested simply tends to determine the beams or the separators on which the floors are warped, where the balconies are disposed and where eventual walls rest (perimeter and/or internal). The separators can have any type of form, and the balconies can even occupy a limited portion of the beam. Moreover, the user may explicitly define the value of the load agent on the elements in question. So, the program will perform an automatic analysis of the loads, also giving the possibility to insert other load elements whose value is set by the user (concentrate loads are foreseen Fx, Fy, Fz, Mx, My, Mz; distributed loads; distributed out of shape moments; horizontal pressure on the separators). Information about the weights that are discharged on the beams due to the loads imposed by the designer can always be requested. Once the definition of the loads is exhausted, the floors on the plan can be identified by simply defining the lines of the section. Disassamento travi con mouse.Disassamento effettuato.This simple operation allows an automatic link with the CDFWin program, in order to calculate the floors and staircases and the automatic drawing of the irons on the carpentry plant. The interface simplifies the work connected to the calculation of the floors, as the procedure generates the data for the program CDFWin automatically (geometry of the floor, entity of the loads, changes of loads according to the lines of impact of the floor being examined, etc.). Once launched, other than performing the calculation of the floors, it allows the print out of the calculation tables, which are perfectly congruent with those provided by CDSWin, and also returns the carpentry of the plan with the exploded view of the irons of the floor and the assembly of the drawings in tables for the plotter; all is perfectly congruent and integrated with the outputs of CDSWin to provide complete project attachments that can be easily interpreted. The space generation phase transforms the data from the plank format to the format that can be re-read from the initial space input. The generation phase performs a series of controls on the validity of the data input provided, and in absence of restraints defined by the user, it automatically creates all of the restraints of the structure; Moreover, the generation automatically defines the mesh of the bi-dimensional elements; in case of adjacent members of shell elements, a corresponding mesh will be created even for the members, in order to guarantee congruity of movements. The structural elements (members and shell) divided by the generation phase, will be automatically re -united in the drawing phase of the final drawings.

 

SPATIAL INPUT

The spatial input mode, which directs itself to the definition of structures that are particularly complex is articulated in the following phases:
1. Graphic regulation
2. Archives
3. CAD Import/Export
4. Nodes
5. 3D Members
6. Shell elements
7. External restraints
8. Internal restraints
9. Load conditions
10. Member loads
11. Node loads
12. Shell loads

Scala a chiocciola realizzata tramite una copia roto-traslazionale.In all the phases of the program, one can operate on generic levels, oriented in space (work levels); the management of these levels allows the insertion of nodes in local coordinates, with notable simplification of the input of complex structures. Also, a clipping function is active in all phases, which allows the visualization of a portion of the structure; the partialization of the visual can be requested on xy level, along the z axis, even on a work level defined by the user. With the multi-window management, one can contemporarily visualize different points of view and different portions of the structure. The 3D node structure allows the insertion and modification of nodes in space. If a work level is activated, insertion takes place via coordinates of local reference of the Pdl, or else the coordinates are referred to by the global reference system. The 3D member phase allows the insertion and modification of members located anywhere in space. To ease the insertion of the members in series with equal attributions (rotations, offsettings, type of section, etc.), a "current element" has to be defined and the following members can be created by only specifying the initial and final node. Copia delle caratteristiche di un'asta.A member can also be divided in more parts by choosing the number of subdivisions and using the Aexplosion@ function of the members. The elements shell phase allows the insertion and modification of the bi-dimensional elements available in space. In particular, one has the possibility to choose the internal mesh space of any shell element on every side is highlighted, as well as the possibility to Aexplode@ a shell element in more independent sub-elements that can be divided, modified, or cancelled. From the archive phase one accesses the metallic profile management. The archive manager of the metallic sections allows the input and the correction of the relative metallic topologies in the technical practice, both as simple profiles, as well as coupled. An archive is provided along with the program, with approximately 1000 metal profiles already inserted. It=s worth nothing that the input of eventual new profiles requires a minimum insertion of data, as only the geometric data of the section must be provided to automatically obtain the relative static sizes associated for the calculation. Obviously, the values of inertia, static moment, etc., calculated automatically can eventually be corrected and set by the user. The same procedure allows the insertion of wood members that are also verified. The import/export phase allows the construction of substructures on external CAD, and their import in the structural CDSWin context. For this objective, the program WinCAD is equipped with specific functions that allow the parametric creation of reticular beams. The frames created with WinCAD or with external CAD can be inserted on a generic level of space that is inclined, specified by the user. The spatial input was equipped with powerful copy functions of structure blocks (shifting, rotational and roto-shifting) and of attributes of a structural element to a group of other elements.Carpenteria del piano quotato.All the phases are equipped with a specific undo function, which allows the structure of the previous situation of the operation performed to be restored; this allows for work to be recovered even in case of large mistakes made in the input phase. The internal and external restrain phase is equipped with great flexibility. The restraints can be predefined (hinges, notches, plum-rule, etc.) or built directly by the user. In particular, the external restraints can also be inclined and moved with respect to the natural node. The graphical representation of the restraints can use icons and symbols; as an alternative you can visualize a triplet of versors that highlight the directions of the vector plants released from the restraint. In case of level truss sub - structures, a new function can be used to automatically define the restraints (or the hinge at the extremity of the members, with vector orthogonal plank on the truss level). An important innovation is constituted by management of multiple load conditions. This allows us to separately analyze the loads due to independent conditions, such as those for example that derive from snow, winds, thermal, etc. These conditions can be in any case combined via multiplication coefficients to be set in the pre-calculation phase. Regarding the member loads, trapezoidal distributed loads are foreseen in any direction (x, y, z), both in the local reference system, as well as in the global concentrated loads (forces and couples) can be inserted in any 3D node and in any direction. Shell loads allow the insertion of trapezoidal pressures and distributed lateral loads. All types of loads are equipped with a graphical representation that is proportional to the entity of the load.

 

SOVER AND POST-PROCESSOR

Visualizzazione multifinestre di una struttura reticolare in acciaio.After data entry has terminated, the program generates a structural input model from the data, contemporarily performing a check on the correctness of the data inserted. The solver, integrally developed by STS in a Windows 32 bit environment, was optimized to fully take advantage of the last generation computer resources, achieving a notable calculation speed. It=s important to underline that CDSWin=s license fully covers (other than the structural CAD for the input and the post-process graphics), even the solver, as long as it was not derived from others (see SAP IV or similar), but fully developed by STS, who is the legitimate and exclusive owner; this places the user of CDSWin in full regularity with respect to the norms that regulate the software rights, that constitute a crime of civil, criminal and fiscal nature for the holders of software not regularly authorized. The solver incorporates advanced algorithms for the reduction of the band width of the rigid matrix, which represent the state of the art of this matter. The dynamic analysis, with or without rigid plank, is performed with a method of interactions in the SOTTOSPAZIO. The seismic calculation of the structure of rigid planks is automatically enveloped with a thermic resolution (without rigid planks). The plinths, both direct than on piles, are schematized in the model with equal rigidities. Furthermore, more conditions and combinations of definable loads are managed as the user pleases. In case of non -linear calculation, the instability, both local than global, is already taken into account in the resolution phase (P-Delta effect).

 

CHECKS

Verifications of the resistance, conducted in accordance to the terms of the Italian law adapted from D.M. of 16-01-96 and of the memorandum of 10-04-97, follow the directives imposed by the user via appropriate project criteria, which can be managed member by member. Various parameters can be differentiated through the project criteria, such as the characteristics of the materials, type of clamping (only clamps, clamps and wall irons, clamps and bent irons according to the percentage decided upon by the designer), diameters and clamp arms, diameters of clamp supports, rigidity torsional percentages, and many more, which determine the resulting reinforcements.Visualizzazione a colori della quantità di armatura richiesta per ciascuna asta.One can choose between appraisals of the allowable stresses and appraisals of the ultimate limit state and of the serviceability limit state. An appraisal in accordance to the Eurocode 2 is also available for concrete members, as well as Eurocode 3 for steel members. The certification of the distortions have been made more powerful by calculating the viscous effect on permanent loads even for rare combination loads. The project of the reinforcements in the beams, takes into account both the minimum legal requirements, both the minimum values imposed by the criteria of the project (for example gl2/n). In case of "T" beams or "L" beams of foundations, the program provides support up until the clamping of the wing is sufficient as reinforcement for the flexure induced by the tension on the ground. Colormap di un setto shell.The project of the columns can occur, on the user=s indication, both as a regime of a straight presso-flexure, as well as deviated. Eventual columns or beams that have been subdivided in sub-elements for modeling requirements, are automatically re-united during the verification phase, iron drawings and chart prints. Both bi-dimensional vertical elements (separators) as well as horizontal or inclined elements (plate/slabs) are verified by flexure and also via piercing. The appraisal program is equipped with a sophisticated algorithm, which allows the automatic determination, not only of the diffused base reinforcement, but also of eventual thickness that is necessary to cover the top of the reinforcement, in order to avoid useless wastes of iron. The vertical separators can then be mutually connected to form sole structural elements (for example, rigid core), of which a detailed feasible drawing is provided. Particular attention was drawn to the final projects of these elements in reference to the reinforcements of the stapling of the corners, necessary most of all in the presence of the orthogonal pushes on the walls (tanks, underground separators, etc.). The appraisals of the steel members, conducted with total respect of the norms in vigor, are performed both in respect to normal tension (press-flexure), as well as in respect to the marginal tension (shear-torsion); also, verification of the stability according to the Omega method, warping verifications, lateral stability, etc. are also performed.

 

VERIFICATION OF RESULTS

Visualizzazione con colormap dello stato tensionale di un serbatoio cilindrico.The program is also equipped with powerful control procedures of the calculation results, which immediately identify the members that are under-dimensioned, over-dimensioned, or with particular problems; and the visualization of the deformation regimes and/or actions of any structural element (member or slate/plate). The procedure of visualizing results in 3D allows the graphical representation of:
1. Distortions
2 Member diagrams
3 Tensions shell elements
4 Movement shell elements
5 Coloring of verifications
6 Member results
7 Relative movements
" The first distortions" phase foresees a selection between static, seismic, and thermic distortions, relative to the single conditions or load combinations; also, you can choose between elastic distortions and kinematic distortion, and to activate the color map of the distortions, which allows the visualization of the values of the base movements to the coloring.
Visualizzazione dello stato tensionale e deformatibo di una piastra nervata.AAnimation@ mode can also be used, which shows the distortions in movement of the structure, fully using the possibilities of graphic acceleration of the hardware available. The second phase "member diagrams", allows the visualization of the diagrams of the action characteristics (Tx, Ty, N,Mx,My,Mz); even in this phase a color map modality is available, which visually identifies the values of the characteristics based on the coloring.Visualizzazione dei diagrammi delle sollecitazioni.The third and fourth phase "shell tensions" and "shell movements" show the tensor of the characteristics, pressure on the ground and the xyz movements of the shell elements with color maps. The fifth phase "verification coloring", allows the visualization on a color scale of the following sizes for the member elements on : Total iron area, iron density, minimum stirrup. Step - ground pressure- ideal steel sigma- instability steel sigma-steel sigma twist- Non verified members. Also the same procedure allows the non verified shell elements to be highlighted in color. The 6th phase "member results" allows the selection of any member with the mouse and the direct obtainment on video of a print of the results of the flexure verifications, shear, torsion, etc. Still with the color diagram, the movements between the top and bottom of the columns can be visualized, in order to check the limits imposed by the law at that size. These graphic representations avoid a tiring manual analysis of the numeric elements on paper.

 


POST-PROCESSOR

Esecutivo di aste in c.a..once the calculations are performed, graphic post-processors can be used to obtain the final drawings of the structure. The automatic drawing of the final drawings include:
1. Carpentry plans with automatic dimensions
2. Perspective with hidden lines
3. Beam reinforcements even inclined and extrados
4. Plinth and column charts (both direct than on pile and piercing reinforcements)
5. Reinforcements of plates and/or slabs (distributed reinforcements and thickening)
6. Reinforcements of vertical slate-plate elements (with reunifications of single shell elements)
7 Reinforcements of hardening cores
The automatic creation phase of the drawings can be personalized via a series of parameters that optimize the final drawings; for example, regarding the drawings of the final projects of the beams, some of these parameters are:
-parameters of the iron;
-anchorage length
-anchorage shapes (90 degrees, 45 degrees, etc.)
-shape of the bent irons (boat-shaped, U-bolt, etc.)
-maximum distance between irons
-minimum distance between irons
-iron maximum length
-distance to reunite irons
-difference for the unification of the stumps
-existence of distributed folding
-drawing of transverse sections
-hook shape stirrups
-text dimension
-etc.
The graphic post process includes the software module that interactively personalizes the final drawings, via dedicated CAD. These manipulations are performed by the user thanks to the use of the comparison of the diagrams of the reinforcements of the calculations with those drawings, optimizing in this manner the distribution of the reinforcements of the manipulated elements, both if they are members, as well as bi-dimensional elements. After having performed the final drawings and the eventual manipulation, the elements can also be rechecked with the reinforcements effectively disposed, in order to determine the work tensions. Each final drawing, generated automatically by CDSWin is also equipped with a detailed calculation of material, both for elements in concrete, as well as for those in steel, also exportable on ACRWin's calculation program . It is easy to evaluate the cost of the structure in terms of cement, boardings, iron rods and steel sections.

 

PRINTS

Visualizzazione prospettica di una struttura e della sua deformata.Prints of the calculation charts have been studied to unify the best esthetic aspect, with the maximum compactness, and minimization of the volume of printed paper and printing time. Print procedures of the texts allow output both on old DOS drivers (for compatibility with old printers and more speed on pin printers in text format), both with Windows drivers in graphic mode. You can also address the print on file (in Ascii or Rtf format) and on video with an optional graphic preview. The calculation report can be confirmed by the user inserting the normative points of reference, the extended explanation of the symbols used, the measuring units, compact print and extended calculation results, left margins, right beginning and end of page, etc. The program contains a professional editor (WinEDITOR), made by STS, which allows the personalization of the calculation reports generated by CDSWin.
To print out the drawings you can choose between printer, plotter and DXF format. Furthermore, CDSWin is equipped with an internal CAD (WinCAD) to allow the performance of graphic finishing and drawings made by other procedures of the package before being printed. In order to optimize the use of the plotter, a routine that allows the manual or automatic construction of the charts is foreseen, which is complete with eventual squaring of the tables used as headers. The tables that are assembled can be printed directly by CDSWin or transformed in DXF files, which can be re-read by any CAD.


FINAL STEEL PROJECTS

for steel structures, CDSWin offers an optional module to verify the structural nodes in steel and the drawing of the automatic metallic carpentries. This procedure is articulated in the following phases:
1. Definition of the substructures
2 Node definitions
3 Verification of the connections
4 Development of final drawings
Nodo trave-colonna con flangia e ginocchio.In the definition of the substructure beginning with the 3D model that was already calculated, the level substructures are included, which are inclined in space are isolated, distinguishing amongst framed substructures (frames, planks, etc.) or reticulated work. In the next definition of nodes in the substructures defined previously, you choose the last extreme of one of the members in the connection (generally the support member). So, you can select a topology of nodes amongst those foreseen by the program, which are precisely the following:
1. BeamBeam Rest (Square Core)
2. BeamBeam Continuous (Square Core and wing joint)
3 Beam Column Rest (Square on core Column)
4 Beam Column Rested (square on wing column)
5 Hinge Plinth Column (plate and anchor)
6 Hinge Brace (gusset plates and bolts or welding)
7 Beam Beam or Column Column Set (joint)
8 Beam Beam or Column Column Set (double joint)
9 Beam Beam or Column Column Set (with flange, even for inclined beams) and with eventual bend
10 Beam column set (with flange, even for inclined beams)
11 Column plinth set (plate and anchors)
12. Hinge unification for bolted reticular works (gusset plates and bolts)
13. Hinge unification for wedged reticular works
Once you select the program, immediately indicate the topologies compatible with the extremities of the member selected. For each topology, a screen of graphic help can be visualized that expresses the meaning of the single parameters.
Definizione nodi.Therefore, we move on to a geometric dimensioning of the node; in this phase an interactive visualization of the personalized node exists: this avoids many development mistakes, seeing the number and the complexity of the geometric restraint in these types of nodes. For each topology a predefined node in archive can be obtained or you can proceed to input new nodes. In this case, the program automatically recognizes the converging members on the union and predisposes a geometric dimensioning of a node, making an apposite window, front, lateral and above view, immediately visible. Archivio nodi: trave-colonna con flangia.All these views are already dimensioned and the number and types of bolts used and the dimension of eventual welding cordons. In this manner, we wanted to reproduce the same work methodology of the designer of steel structures, who even before verifying the node has to draw it to guarantee that it can actually be developed in practice. For reticular work structures, one can also obtain the automatic pre-dimensioning (project phase) of all the connections, both wedged as well as bolted; the automatic project is based on a series of values predefined by the user, who can obtain the optimal and personalized dimensioning in this manner. For all topologies of nodes, a visualization and tri-dimensional photorealistic animations with shadowing is available, which allows an ulterior check on the coherence of the input data provided. Once the nodes have been geometrically defined, the next step is the verification of the connections; the values of the action agents on the extremities of the member converging on the union have automatically passed from the calculation phase of CDSWin, taking into account the conditions and the load combinations, and can be checked by the user and eventually changed. Archivio nodi: trave-trave continua.This allows the calculation schemes of the nodes to be verified (for example you can verify the lack of significant moment agents corresponding to nodes of rest types), as well as that of single nodes who have undergone notable actions even in the absence of a structural context. The verifications performed vary based on the topology of the node and cover all the elements that compose the node, such as: bolts, squares, profiles, flanges, gusset plates, wedges, etc. For example, the following verifications are performed:
1. Profiles and unification elements A RIFOLLAMENTO
2. Shear and traction bolts
3. Plate and flanges presso/flexure
4. Perforated profile sections
5. Wedging involved in the connections
6. Restoring joints or tension calculations
7. Shear and flexure squares
8. Core panels of flange nodes
9. Anchors
10. Rib work diagonal core panel
11. Shear ribbing of the base plate etc.
The visualization of the results allows graphical highlighting of the nodes in which the verifications haven=t been completed, with different colors. Furthermore, a node to visualize the relative results can be selected graphically. Lastly, we access the Production phase of the final drawings and charts.
Esecutivo di una reticolare.The results of the verifications can be printed on video, file, or printer, in order to check that the dimensions adapted are correct. In order to make the analysis of the results easier, some synoptic squares are presented, which group the nodes verified in the various topologies they belong to and immediately it=s easy to comprehend where the verifications did not take place. It is worth noting that the prints include some detailed charts of calculations of materials of every sub-structure. The final drawings of the structure can be on video, dxf file, plotter, or graphical printer. The following can be obtained automatically:
1. Drawing of the single - wire diagram of the frames or reticular works with indication of the profile used and relative length, identification number of the part of the metallic node and total dimensioning.
Particolare nodo trave-trave continua.2. Final drawing and reticular work structure or latticework, with real dimensions and dashed view of the hidden lines, indication of the profile used and relative length, insertion of bolts, dimensioning of the bolts and entire total.
3. Final drawing of the frame, with real dimensions and view of the profiles with a dashed-line of hidden lines, indication of the profile and relative length, identification number of the detail of the metallic node and the dimensioning.
4. Automatic drawing of the detail of the complete nodes of dimensioning, marks indicating number and dimensions of bolts and welding, and the identification number of the detail of the sub-structure.
5. Automatic drawing of the three-dimensional view of the nodes with shadowing even in animation. In particular, regarding the final drawings of frames and reticular work, it should be noted that the program takes into account the permeations and reunifications between the profiles present in the calculation scheme. In case of drawings of nodes of reticular works, the program is automatically able to trace the gusset plates that can be chosen amongst rectangular or polygonal. Via the module "Board Assembly", everything can be united automatically in complete table theme boards, including all of the drawings of the structure in steel.
