3D simulation of a steel joint
Steel joint is composed from plates, welds, bolts, contacts and can be anchored into concrete block. FEA model is generated automatically.
Model is composed from steel plates – both parts of steel members and stiffening plates. Real shape of plates is kept.
Each plate is meshed independently. Equivalent strain is checked.
Contacts appear in places where two plates are in touch. They take 100% of the pressure but do not act in tension at all.
Steel structure can be anchored into concrete block. Base plate is in contact with concrete. Tension is taken by anchors, shear by bolts, friction or shear iron.
Local buckling can determine safety design of the joint. Software shows the level of safety and point out the weakest part of joint.
Welds are modeled as constrains between plates. Forces in each weld are evaluated. Stress in weld is checked according EN/AISC.
Bolts are nonlinear springs taking tension and shear.
Stiffness of any connected member is analyzed. Connection is classified and moment/rotation diagram gives clear view about its capacity.

New CBFEM method inside changes the game of structural joint design
Together with two top technical universities, we created a new method for analysis and check of steel joints of general shapes and loading. It is called Component-Based Finite element model (CBFEM). After 5 years of primary research and theoretical preparations, the first version of the application was coded in 24 months and released in May 2014.
How CBFEM works
We combine two well-known and trusted methods used by engineers all around the world – finite element method
and component method:
- Joint is divided into components
- All steel plates are modeled by finite element method assuming ideal elastic-plastic material
- Bolts, welds and concrete blocks are modeled as nonlinear springs
- Finite element model is used for analyzing internal forces in each of the components
- Plates are checked for limit plastic strain – 5% acc. to EC3
- Each component is checked according to specific formulas defined by the national code, similarly as when using component method
Validation and verification
Results of all tests performed to confirm safety and reliability of CBFEM method and IDEA StatiCa Connection are published and available. Visit our website to examine them. Professor Wald and his team are also publishing a book devoted to structural steel connections design using CBFEM method:
