Behavior of frame-corrugated steel plate shear wall structure under cyclic loading

Abstract

This manuscript innovatively presented a new type of assembled H-shaped steel frame-corrugated steel plate shear wall (HCSW). The hysteretic performance of assembled HCSW under cyclic quasi-static loading was investigated. The HCSW specimens with different corrugated steel plate thickness and axial compression ratio were fabricated. The H-shaped steel frame-flat steel plate shear wall (HPSW) was fabricated as control test specimen. The failure process, hysteresis curves, skeleton curves, lateral capacities, energy consumption and the other issues were discussed. The hysteretic performance of HPSW and HCSW was compared. It could be found that the hysteretic performance of HCSW was better than that of HPSW. The corrugated steel plate was yielded prior to frame column as a desirable sequence of material yielding. In addition, the finite element model was established to simulate hysteretic performance of HCSW specimen. The parameters included width-to-thickness ratio, width-to-height ratio, and axial compression ratio in this research. The effects of parameters on HCSW hysteretic performance were analyzed and discussed based on the finite element model. According to the research results, the recommended values of parameters were proposed based on the analysis results. Furthermore, the calculation formula of HCSW initial stiffness was presented. This research could provide a reference for the design and evaluate the application of current design of provision for assembled HCSW.
