STEEL Connection

Design and code-check of steel connections and joints

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.
