Iterative calculation of design load of the joint. Rotational and axial joint stiffness (rigid, semi-rigid and pinned) and joint characteristics – initial stiffness. The coefficient of critical load with the corresponding deflection shapes. Linear analysis of stability of the connection elements. The load is applied in increments, the corresponding stress and strain is calculated and evaluated. Prestressed bolts and plastic behavior of the welds are also taken into account.Īnalysis of stress and strain of all connections and joints. Modeling considers an elastic-plastic material model for all the elements of the joint – plates, elements, bolts and welds. We provide clear pass / fail checks according to EN/AISC/CISC/AU/SP 16 standards in a complete report with drawings.įor analysis, the unique CBFEM method based on finite elements is used. IDEA StatiCa Connection designs and checks welded or bolted connections, 2D or 3D joints, anchoring or footing of all topologies.
