Abstract

In this study, the structural behavior of coupled shear panels with Easy-Yielding steel plates is thoroughly investigated. These advanced systems are designed to enhance energy dissipation while ensuring a controlled and predictable yielding mechanism in seismic-resistant structures. To this end, after introducing the design assumptions, three one-story, prototype-scale numerical models with Shear, Intermediate and Flexural link beam behaviors are designed using the Plate-Frame Interaction method, and the corresponding analytical formulations are derived. The selected configurations effectively capture diverse force transfer and deformation mechanisms typically encountered in practical engineering structures. Subsequently, the specimens are modeled in Abaqus software and subjected to nonlinear static analysis to verify the yielding sequence of structural members and evaluate the overall nonlinear response. Pushover curves are extracted afterwards and systematically analyzed to assess strength capacity and overall deformation characteristics. The results demonstrate that the proposed analytical formulations are fully consistent with the numerical simulations performed in Abaqus, as both approaches predict the same yielding sequence of structural members, which is a primary objective of the design.
