Abstract

Highlights: The cyclic behavior of the corrugated steel plate (CSP) link was tested and validated. The corrugation can provide adequate out-of-plane support to the steel plate. The effect of geometric parameters on the seismic behavior of CSP was investigated. Finite element simulation with ABAQUS can reliably predict CSP's nonlinear behavior. The proposed simplified equations can effectively predict the capacity of CSP. Abstract: In this paper, a novel replaceable corrugated steel plate (CSP) link is proposed. Eleven specimens with different geometries were tested. The results show that the yield lateral load and initial stiffness of the specimen were mainly affected by the aspect ratio of the CSP. On the other hand, the peak lateral load, ductility, and energy dissipation were closely related to the depth and aspect ratios of the corrugation. Robust finite element models were built to simulate the hysteretic behavior of the CSP. The result shows the finite element models were capable of simulating the cyclic response of CSP well. To facilitate design efficiency, simplified equations were proposed to predict the yield lateral load, peak lateral load, and initial stiffness of the CSP. The results show that these equations can be used efficiently to predict the capacity of CSP. Overall, this study provides a comprehensive experimental and analytical study to show that the proposed CSP link has stable seismic performance and can be used as an effective steel link for seismic applications.
