EN 1992-1-1.
Steel structure checks according to DIN 18800 and EN 1993-1-1 (elastic-elastic, elastic-plastic and plastic-plastic). Lateral torsional buckling check according to DIN 18800 and EN 1993-1-1. Timber checks according to DIN 1052 and EN 1995-1-1. Section analysis for polygonal beam sections; profile database. Eigenvalue determination, time-step integration, dynamic train crossing, nonlinear cable dynamics. Response spectrum method for earthquake check according to DIN 4149, EN 1998-1, OENORM B 4015 and SIA 261. Thermal analysis of steel, timber, reinforced concrete and composite sections. Stability check under fire conditions
according to EN 1992-1-2, EN 1993-1-2 and EN 1995-1-2.
Prestressing of beam and shell structures as well as solid modells. Prestressed concrete checks according to DIN 1045-1, OENORM B 4750, SIA 262 and EN 1992-1-1. Bridge checks according to DIN Technical Report 102 and EN 1992-2. Computation of construction stages. Data exchange via DXF, IFC, steel construction and reinforcement interfaces.
Model editing, analysis control and results output for all structure types are performed in a standard 3D CAD user interfacethat includes functions familiar from Windows.
InfoCAD manages structures in project files. The information contained in a project file is organized in data sets which youcan access from the graphical view, the table view or the File Service command in the File menu. The structure type isdefined for the project file and labeled by a file extension (FEM, etc.) in the Structure menu. One static system of thefollowing structure types can be stored in each project file:
Finite Element System (FEM) 3D Frame (RSW) 2D Frame (ESW) Axisymmetric Shell (ROS)
The static system includes the specified structure data such as beams, area elements, tendon groups or section values alongwith their associated loads. The computation modules identify deformations, internal forces as well as support and soilreactions and store that data together with the check logs in the project file. This means all the results for output andadditional processing are available in one central location.
The program also allows you to create and save help diagrams and explanatory notes in the project file.

Installation and Configuration
Installation and Configuration
LicensingThe program system can be used with a single user license or a network license. Each license is protected by a softwarehardlock.
Single User LicenseWith single user licenses a software hardlock is required at each workstation. Hardlock usage via remote connections is notsupported. If several workstations are set up with different licensing configurations, then each configuration will require itsown hardlock. You can check the current licensing configuration at the workstation in the licensing information provided inthe Help menu. Functions that are not licensed are disabled in the interface.
Network LicenseNetwork licenses do not require a software hardlock at the workstations. The licenses are managed by the InfoGraphLicense Manager, which is installed on a central licensed computer together with a special network hardlock. The programusers can access the software from any workstation in the network.
Single User LicenseInstallationInfoCAD can be installed on 32/64-bit computers with Windows XP/Vista/7/8/8.1. All installations require administratorprivileges. Windows will automatically run the installation program when you insert the CD. Alternatively, you can runSetup.exe directly from the CD. The customer license number indicated on the back of the CD box is required for eachinstallation.
Click the following options from the Installation menu:
Install hardlock driver.This device driver is needed for the software hardlock to work.

Single User License
User ConfigurationThe user settings are managed in the following files:
IGRAPH.DATThe basic settings of the computer programs, user-defined page formats and other printing settings are stored in thissystem file. The file is automatically created in the 'C:\My Documents\name\Application Data\InfoGraph' (Windows XP) resp.'C:\Users\name\AppData\Roaming\InfoGraph' (Windows Vista/7/8/8.1) folder when InfoCAD is opened for the first time,where "name" represents the login name of the user. These folders carry the 'hidden' attribute and are displayeddepending on the folder options setting.
ANWEND.PROThe user database lets you store user-defined beam sections. It is created in the 'My Documents\InfoGraph' subfolder of theuser.
If all users are to work with the same settings, the administrator must manually copy this file to the program directory. As aresult, users will no longer be able to change the settings.
Language SelectionDuring installation you will be prompted to select the language of the user interface. You can change the language at anytime in the Options menu. The analysis logs and results will now be displayed in the language you have selected.
Design Codes
The design codes shown in the user interface are preset according to the country setting of the operating system. You canchange the selection at any time in the Options menu.
Page FramesThe page frames used for printing can be selected in the Print dialog. Except for the standard page frame, you can design oradjust any of the frames that are available for selection using the Page Frame option in the Options menu.

User Interface
Dialog BarThe functions in the menu extend the range of input options when using the dialog bar. They are as follows:
The provided buttons can be accessed with the left mouse button.
You may enter data into the input field using the keyboard. If the text cursor is not in the input field, simply click thefield to move it there. Conclude all data inputs by pressing the Enter button or key. Right-click to access a contextmenu.
You can cancel dialogs by pressing the Esc button or key.
Coordinate InputObject coordinates are saved in InfoCAD using three components. You can enter the coordinates using either the crosshairor the keyboard.Crosshair input is carried out in the representation area. In 2D view the third component is specified based on the constantsthat have been defined for the viewport (e.g., the constant z value for the xy viewport). Object points near the crosshair aresnapped automatically. The effective snap radius can be defined via the Snap menu.If you enter coordinates using the unit meter in the dialog bar with the keyboard, separate the individual components witha space. The decimal separator must be entered in accordance with the regional settings of the operating system. You candefine a local reference system for coordinate input using the Snap menu functions.
The following input variants are available:
Cartesian coordinatesAssign the first two values to the axes of the viewport in 2D view (e.g., x and y). The constant specifically defined for thatviewport will be used as the third component. In 3D view, coordinates must be entered in the order x, y and z. The &character can be used to define relative coordinates which refer to the previous point.
Example: In the xy viewport, entering '& 1.55 3.05' will yield a point with Dx=1.55 and Dy=3.05 relative to the lastpoint.
Cylinder coordinatesSpecify radius [m] and rotation angle [] against the horizontal axis in 2D view (polar coordinates). In 3D view, the radius,the rotation angle against the x axis and the z component are required. The angles are defined in a positive, clockwisedirection.
Example: In 3D view, entering '1.4142

client such as MS Outlook is installed.Only Input Data Button for sending project files via e-mail.Exit Close the current project file and exit the program.
Construction StageThe Construction Stage function supports the calculation of structures in which different construction phases are to beanalyzed. The function is based on the following principles:
1. The calculation model of each construction stage is stored in a separate project file.
2. The names of associated project files are identical except for a consecutive number. The file name for the firstconstruction stage must contain the number (1) (e.g., 'System(1).fem'). This is required for the function to work.
3. The program assigns an attribute to the project files to ensure their coherency. Hence there is no need to bypass thesystem to add or delete construction stages.
4. When creating a new construction stage, the program simply uses the current system without the load cases. The newconstruction stage also includes the number of 'inherited' elements, nodes, supports and tendon groups as well as theload cases of the previous system. In the case of 'inherited' tendon groups, the Ignore in prestress load button isselected.
5. The structural components in the new construction stage can be added or removed in any manner you choose. Doingso will have no effect on the object numbers included from the previous stages.
6. The section and material properties of transferred elements may be modified.
7. You can define any number of new load cases (recorded load case numbers are protected).
8. The settings regarding the number of result locations in the beams and the result locations in the area elements mustbe the same in all construction stages.
24
User Interface
9. Before each calculation (finite elements or framework calculation), the results from the load cases of the previoussystem are applied to the current system. This process only takes into account the included objects (see 4.). Morespecifically, this involves:
Node deformations (DEFORM.*) Beam deformations (ELDEF.*) Support reactions (AUFLR.*) Deformations in the support system (AUFLDEF.*) Internal forces of the beams (SREAK.* / LERG.*) Internal forces of the areas and stresses of the solid elements (REAK.*) Soil pressures (SIGB.*) Resulting soil pressures (SIGRB.*) Tendon group forces from creep and shrinkage (VSPZV.*)
10. The transferred results are available in the standard form for additional processing. This includes the superposition orthe combination with other load cases, for example.
The buttons of the Construction stage dialog have the following functions:
CloseClose the dialog.
NewInsert a new construction stage behind the open and selected construction stage.
OpenOpen the selected construction stage.
DeleteDelete the selected construction stages that follow the currently open construction stage. These deletions are permanent.You will be prompted to confirm the deletions.
EditEdit the selected construction stage.
The left dialog shows the load cases and structure objects whose results are taken over from the previous construction stagefor each calculation process. During the creation of a new construction stage, the marks for all load cases and structureobjects existing at this moment are set automatically. If in previous construction stages load cases are added subsequently, atake over of the results to the current construction stage only occurs if the new load cases are marked here. Results of anew structure object can only be transferred if it exists in the current construction stage with the same number and it ismarked for transfer.
The right dialog shows the identifiers connecting the current construction stage with the previous and subsequent one. Theidentifier is automatically defined by InfoCAD for every project file and persists after renaming of the file. A constructionstage can be deleted or added to this chain by replacing the identifier of a previous or subsequent construction stage.
The usage of these functions is to be limited to exceptional cases. It can result in overlapping of load case,element and node numbers and as a result, it can lead to an unwanted mixture of results. The user isresponsible to prevent this overlapping.

IFC Data Transfer
The data transfer is based on the IFC version IFC 2x3.
Coordinate SystemIn the IFC product model the z axis of the global coordinate system typically runs from below to above. This is counter tothe convention used in InfoCAD. To avoid all objects standing on their heads after an export or import, they are turned 180around the global x axis.
ImportThe data import consists of two functional areas: Importing the Analysis models (frames or model objects) Importing the Geometry of Building Elements
1. Importing Analysis models (frames or model objects)
The import is carried out for the static analysis models (IfcStructuralAnalysisModel) saved in the transfer file and selected bythe user. The following table displays the relevant objects.

Dialog for selecting the import data Imported framework
The file contains a analysis model with the name Loads and Results Exported from GTSTRUDL and also building elementsof various types that have been deselected for import.
2. Importing the Geometry of the Building ElementsThis functional area calls for construction model objects saved in the transfer file whose type is derived fromIfcBuildingElement. They include, for example, IfcBeam, IfcColumn, IfcSlab and IfcWall(StandardCase). Only objects with thegeometric display SweptSolid, Clipping, Brep, and MappedRepresentation are considered. In InfoCAD special drawingobjects are generated from these that make it possible to continue to use the geometry of the building elements. The snapmodes End, Middle, and Normal allow you to use, for instance, characteristic points for measurements or for the design ofmodel objects.

The figure above shows several further characteristics that are imported in addition to the geometry of the buildingelements. These include GlobalId: identification of the building element Name, Descrip.: description Material: assossiated material description LoadBe(aring): displays whether the element bears load (1) or not (0)
Transformation into Model ObjectsImported drawing objects whose geometric display is based on the extrusion of a base area (IfcExtrudedAreaSolid) and whooriginate from IfcBeam IfcColumn IfcMember IfcSlab IfcWall(StandardCase)
can be transformed, with the help of the program, into model objects (select Convert from the context menu, FEM mode).As part of this process, linear elements are turned into edges with the meaning Free beam. The generated beam sectioncorresponds to the profile definition used for the base area. Objects originating from IfcSlab and IfcWall whose base areaconsists of a traverse with exactly four points are converted into model surfaces.
The following illustration displays some of the building elements from the file AC-90Smiley-West-14-07-2005.ifc, as well asthe resulting model surfaces. Source http://www.iai.fzk.de/www-extern.
A
Geometry of the building elements Model objects, not joined
Because the model objects are created based on the wall or slab axis surfaces, gaps usually existsbetween neighboring objects (see detail).
As a remedy, all objects are joined with one another during the transformation and, if necessary,marginally reduced or enlarged. If for walls standing on top of each other the wall axes do not matchup, for instance due to differing wall thickness, it might be necessary to add transition surfaces thatare not perpendicular. In addition, openings that are close to the edge are adjusted.
A
The described operations help to improve the continuity between the model objects. This can eliminate the need for manualcorrections in many cases. The following illustrations show the joined model objects and the element mesh that has beencreated as a result.

File ServiceAll input and results data are stored and managed in the project file as data sets. The file service represents the table ofcontents of the data sets in the project file. You can also use it to delete, copy or rename data sets. These actions arepermanent and cannot be undone. Improper use may make the project file unusable.The data sets can be sorted according to the terms in their headers. The menu includes the following functions:
File, Delete ResultsDelete all analysis results.
File, CompressDuring compression unused parts are removed from the file. This can reduce the amount of space the files use on the harddrive.
Records, Copy, Delete, RenameWith these functions you can use the * wildcard to select groups of data sets (e.g. LOAD.*).

User Interface
Undo / RedoYou have the option of canceling the previous changes you made to project data. Any action that is canceled in this mannercan also be restored.
CutThe cut function allows you to transfer and save selected objects to the clipboard for insertion at a later time. This functionis disabled if non-transferable objects are selected.
CopyThere are two ways of using the copy function:
Copy selected objectsThe selected objects are copied to the clipboard and stored for insertion at a later time. This function is disabled if non-transferable objects are selected.
Copy a rectangular image sectionWhile holding down the ALT key, you can use the left mouse button to create a selection box in the drawing area. Whenyou use the copy function, the image section will be saved to the clipboard as a WMF file and can then be transferred to theanalysis logs. You can also use this method to export graphics to other programs that support the WMF format.
InsertObjects saved in the clipboard are inserted with their 3D coordinates. This will replace any objects you have selected. Youcan move the inserted objects to place them at any specific position you want.
DeleteAll selected objects are deleted.
SelectThis function is used to select objects. Selected objects are displayed with dotted lines.
Selection
Objects Selection of individual objects using the mouse.
Number Selection based on a number (beam, element, tendon group, load line).
Window Selection based on a window. All objects that are completely within the window will be selected. If thewindow is dragged from right to left, all objects within the window plus any objects crossing theboundaries of the window are selected.
4P Search region with four points. All objects that are completely within the area will be selected.
last Selects the object specified last.
Switches from deletion mode back to selection mode.
Special features for object selection
Areas and solid elements can also be identified inside an element. Text must be identified within the area that is limited by the text. The option 'Object selection with crossing window (from right to left)' in the snap settings can be deselected.
37
Edit
Select GroupWith this function you can select the objects based on logical aspects. This also enables direct access to individual objectgroups, even for complicated structure models. Using AND logic, all objects are selected that meet every specified condition.
Select AllSelect all visible objects.
Deselect AllDeselect all visible objects. This command can be assigned to the edit men or to a shortcut key using the functionCustomize of the view menu.
MoveYou can move selected objects using the following methods.
Displacement vectorMovement through displacement. The displacement vector is defined by two points.
RotateMovement through rotation. A rotation point is defined in 2D mode while a rotation axis is defined in 3D mode.
MirrorMovement through mirroring. A mirror axis is defined in 2D mode while a mirror plane is defined in 3D mode.
ScalingMovement through scaling in the global or local reference system. You can align objects on an axis or plane by specifying ascaling factor of zero.
38
User Interface
Copy DirectlySelected objects can be copied using the following methods.
Displacement vectorCopying through displacement. The displacement vector is defined by two points. The Multiple option allows you to makemultiple copies of the selected objects.
RotateCopying through rotation. A rotation point is defined in 2D mode while a rotation axis is defined in 3D mode.
MirrorCopying through mirroring. A mirror axis is defined in 2D mode while a mirror plane is defined in 3D mode.
ParallelLines and model edges can be copied through parallel displacement.
GenerateSelected objects are generated through displacement, rotation or a mixture of both. The original objects are always includedin the number of objects to be generated.
Displacement vectorGeneration through displacement. After you specify a displacement vector, the generation will take place in orthogonalform through the incremental addition of the displacement vector components (see image to the left). The specified numberof copies will also be generated if the component equals zero in a direction. This may result in an overlapping of the copiedobjects.After you specify a second displacement vector (and a third one in 3D mode), an oblique generation will be carried outthrough the incremental addition of each displacement vector (see image to the right).
Global generation Oblique generation
RotateGeneration through rotation. A rotation point is defined in 2D mode while a rotation axis is defined in 3D mode.
39
Edit
PolarThe generation is carried out by means of rotation around the specified rotation angle [] and subsequent translation withthe displacement vector. This allows you to create a helix, for example, in a 3D layout.A stair step was initially specified as the prototype in the illustrated example. This step is incrementally rotated around theP1-P2 rotation axis through polar generation and then moved to the level of the next step with the P1-P3 vector.
ColorThe color can be predefined for objects to be created or modified for selected objects. The current color is shown in thetoolbar. If objects are selected, their color will be displayed.
LayerAll graphical objects have a layer property to put them into logical groups. A Layer is identified by its number (from 1 to255). For a description label can optionally be specified. For the graphical representation specific layers can be switchedinvisible, i.e. all objects with this property will be hidden. The layer property is also applicable for locking layers. Afterwardsthe affected objects are still visible but cannot be modified.
New objects get a layer preset by the user when they are created. It can be changed anytime later.
There are different controls for the management of layer properties of objects:
Combination list box in the standard bar
Dialog which is accessible using the layer button in the standard bar or the edit menu Layer pane

Line TypeThe line type can be preset for new objects or modified for selected objects.
Style
You can choose from the following line styles:
1 Solid
2 Short dashed
3 Long dashed
4 Dot dashed
5-15 Solid
WidthSpecify the line width for the objects. Alternatively, you can use the line width that has been defined for the object color(see Print).
ModifyThis function can be used to modify the properties of selected objects (text, solid, circle, arc).
Text
Position Define new text position.
Direction Specify point in the direction of the text or align the text horizontally.
Height Change the text height [m].
Font Change the text font. You can use Standard, Standard mono, Text or Text mono vector fonts as well astrue type fonts. Vector fonts of type mono have a fixed character width.
Text Change the content of the text.
2D solidChange the corner point of a solid.
Circle, arcChange the radius.
Solid
Simplify Add surfaces of a solid together, if they are in the same plane and touch each other.
Remove ports Remove holes from solids.
Divide Solids are cut into pieces by a defined plane.
Add Solids which touch or penetrate each other are added together to one solid.
Subtract Subtract a solid from another solid.
Example of the subtraction of two solids.
Modify LengthYou can use this function to modify the length [m] of a linear object that has been selected. The endpoint of the object thatis closest to the selection point will be changed.
Modify EndpointWith this function you can change the endpoints of selected objects (lines, arcs, edges, holes, solid). The endpoint of theobject that is closest to the last selection point will be changed. The radius of arcs will remain unchanged.
41
Edit
IntersectYou can use this function to intersect selected objects (lines, arcs, edges, holes, walls).The figures below provide four examples of how lines and arcs are intersected. Proceed in the following order: Select the object to be modified at the end that you want to intersect (point 1). Activate the function. Select the limiting object (point 2).
The figures below show you the steps involved in intersecting walls.
Wall ApertureThis function allows you to insert an aperture in the selected wall. The resulting ends of the wall axes are connected by anedge object. The length of both of the resulting walls must measure at least half of the wall width since short walls maylead to very unfavorable or even improper aspect ratios of the elements during mesh generation.
DivideYou can use the context menu to divide selected lines, arcs, edges, holes and solids.
JoinWith this function from the context menu selected lines, arcs, edges, holes or line supports can be joined to one object. Theproperties of the first selected object remains.
Lines (also edges, holes)The objects must be collinear. There can be gaps between them.
Arcs (also edges, holes)The objects must be on a imaginary circle. There can be gaps between them. The new arc starts at the starting point ofthe first selected arc.
Line supportsLine supports are treated like lines or arcs, but no gaps are allowed.
