Design and code-check of a seismic connection in IDEA StatiCa

Watch how seismic joint input is defined and verified in IDEA StatiCa, focusing on a practical example of capacity design for a beam-to-column connection. In this video, we start with a pre-qualified joint that already passes the standard stress–strain analysis and then continue with the seismic capacity design workflow. Loads are applied based on calculated bending moments and shear forces, including opposite load effects required for seismic checks. The dissipative element is defined on the beam, and the expected position of the plastic hinge is specified according to the structural layout. After an initial failure of the capacity design check, the connection is improved by increasing plate thickness and adding stiffeners, leading to a successful verification. Finally, the results confirm correct behavior, with the plastic hinge forming where expected. Learn more at https://www.ideastatica.com
