FEM-Design 3D Frame Module
 

3D Frame - Stress distribution & deformation.
In Brief
 
Various calculation methods are available for 3D frame structures including: 2nd order analysis, dynamic analysis of eigen frequencies and vibration modes, seismic calculations according to Response Spectrum Analysis, stability and imperfection calculations, steel design and steel checking of bars having linearly variable sections.

 
Structures can be generated with the program’s own CAD tools or imported via DXF/DWG and model-based IFC links. A structure Wizard is also available for creating common structure types.
 
A Section Editor is also available to create open or closed arbitrary shapes for bars, beams and columns used in the design modules. The program performs a very fast calculation of all parameters needed in 3D analysis (e.g. moment of inertia, shear factor, etc.) for the current section.
 
The results of calculations can be shown graphically as graphs in 3D for the whole structure, in user-defined 2D views, or for individual bars, beams and columns. Animation of displacement or vibration is also available.
 
Stability analysis with buckling shape & critical load factor calculation.
Section Editor - Bar section designer.
Calculation of imperfection and global stability analysis
 
The program automatically calculates the probable imperfection shapes in real dimensions for steel bars according to EuroCode 3. This imperfection can be applied together with 2nd order theory. Without reference to material type, you can also run a global stability analysis for the whole structure and obtain buckling shapes with their critical load factors.
 
With "Soft spring" procedures, an automatic check of insufficient supports and connections can be run to solve structures defined as instable.
 
Connections - rigid, hinged and semi-rigid.
Display internal force diagrams by members.
Different connection types

The Point-point connection tool allows different connections at the end points or intersections between connected or crossed bars can be set. With this feature, the real state of eccentric 3D bars or semi-rigid connection of columns and beams can be modelled.
 
Steel design*


The steel design module enables you to check steel bars with regard to 1st or 2nd order theory (together with imperfections) for stresses, flexural buckling, lateral torsional and torsional buckling, for web buckling and flange buckling.
 
Utilization checking of steel bars.
