Abstract. Steel Plate Shear Walls (SPSWs) are an innovative system able to confer to either new or existing structures a significant capacity to resist earthquake and wind loads. Many tests have shown that these devices may exhibit high strength, initial stiffness and ductility, as well as an excellent ability to dissipate energy. When traditional SPSWs are used as bracing devices in buildings, they may induce excessive stresses in the surrounding structure, so to require the adoption of large cross-section profiles.

For this reason, perforated steel panels, which are weakened by holes aiming at limiting the actions transmitted to the surrounding frame members, represent a valid alternative to the traditional panels. In this work, a FEM model of perforated panels has been calibrated on the basis of recent experimental tests.

Subsequently, a parametric FEM analysis by changing the number and diameter of the holes, the plate thickness and the metal material, has been carried-out. Finally, an analytical tool to estimate the nonlinear response of perforated metal shear panels has been proposed.
