On the improvement of steel plate shear wall behavior, using energy absorbent element

Abstract

Abstract. Structural engineers have recognized unsti ened Steel Plate Shear Wall (SPSW) as an economical lateral resisting system due to the post-buckling capacity, energy dissipation, and deformability. This study investigates practical application of an added Energy Absorbent Element (EAE), subjoined to the SPSW in order to improve seismic behavior of the SPSW. The EAE is an aluminum shear panel with or without bracings and surrounding frame. Furthermore, a series of parametric studies are implemented to examine the e ect of dimensions, position, and formation of the EAE. It is assumed that the lateral loading is applied as quasi-static loading. Further, nonlinearity of the material and the geometry are included in the models. The results reveal that by adding the EAE adjacent to the surrounding frame of the SPSW, not only dissipated energy, but also ultimate strength of the system can be e ciently increased.

A Study on the Significance of the Design Parameters of Steel Plate Shear Walls Subjected to Monotonic Loading

“…At the first of emerging, the SPSWs had many stiffeners to avoid buckling and improving the wall's shear bucking capacity. Over decades, scholars have conducted numerous analytical and experimental investigations and realized that post-buckling of unstiffened plates leads to higher ductility and a more efficient manner in SPSWs [6]. Since, under incremental lateral forces, the steel plate is subjected to buckling in shear and forming post-bucking diagonal tension fields.…”
