IDEA StatiCa Connection designs and checks welded or bolted connections, 2D or 3D joints, anchoring or footing of all topologies. We provide clear pass / fail checks according to EC / AISC / CISC standards in a complete report with drawings. For analysis, the Unique CBFEM method based on finite elements is used. Modeling considers an elastic-plastic material model for all the elements of the joint – plates, elements, bolts and welds. Prestressed bolts and plastic behavior of the welds are also taken into account.

Analysis of stress and strain of all connections and joints. The load is applied in increments, the corresponding stress and strain is calculated and evaluated. Linear analysis of stability of the connection elements. The coefficient of critical load with the corresponding deflection shapes. Rotational and axial joint stiffness (rigid, semi-rigid and pinned) and joint characteristics – initial stiffness. Seismicity checks. Iterative calculation of design load of the joint.


No limits in how many connections there are in the joint and how they are put together. Shape is defined by project requirements, not by software capabilities. 


All forces are analyzed. The overall check of the joint takes into account interactions between all the beams and connections. Engineers stay on the safe side all the time.


The whole design and check process is kept short enough to be a part of everyday work of structural engineers and fabricators all around the world.
