Abstract

Objective: Previous studies on steel plate shear walls (SPSWs) have demonstrated their substantial shear stiffness and strength, coupled with considerable ductility and energy dissipation capacity under lateral loads. The distinct advantages of this system over other lateral load-resisting systems have led to its increasing application, particularly in tall buildings. The incorporation of corrugated sheets alongside flat plates enhances the elastic buckling resistance and ductility of the lateral load-resisting system. Consequently, this paper numerically investigates the influence of bolt rows on a four-layer corrugated-flat plate shear wall. Its seismic parameters are examined through numerical analysis, employing nonlinear static (pushover) analysis for their extraction. The results indicate that for corrugated walls incorporating flat plates, seismic parameters such as the ductility factor and over strength factor increase compared to double-corrugated plate shear walls. Furthermore, recommended values for the ductility factor and over strength factor of the four-layer shear wall are 4.55 and 4.8, respectively. It was also observed that increasing the corrugation angle up to 51.8 degrees enhances performance; however, beyond this value, it has negligible impact on the shear capacity of the four-layer shear wall while increasing stress concentration in the boundary elements.
