Experiment and analysis of self-centering semicircular corrugated steel plate shear walls with edge stiffeners

Abstract

This study proposes a self-centering semicircular corrugated steel plate shear wall (SC-CSPSW) based on the conventional semicircular corrugated steel plate shear wall (CSPSW) with edge stiffeners. The restoring force model of SC-CSPSW and the key points affecting the recoverability are obtained by analyzing the mechanical properties of its components. In this study, two specimens with different diameters of SC-CSPSW are fabricated. Subsequently, low-cycle reciprocating loading tests are conducted on the two specimens to analyze their restoration, deformation, and energy dissipation properties. The experimental results show that the recentering performance of the SC-CSPSW with a large arc diameter is subpar than that of with a smaller arc diameter. The SC-CSPSW with a small arc diameter has a better energy dissipation performance than the large arc diameter of SC-CSPSW, and the main frame of the two specimens remain elastic. Additionally, it is observed that the CSPSWs are damaged with several “X" shapes. The refined finite element analysis (FEA) model of the two specimens is established within the ABAQUS environment, and the same loading system is used to analyze the specimens, thus laying a foundation for later analysis on the influence of various parameter changes on the structural performance of the SC-CSPSW. This study presents the results from the test program and compares the experimental results to the refined finite element model; further, theoretical formulas are verified via comparison at the same time.
