Info Study on the seismic performance of buckling-restrained SPSW structure with butterfly-shaped links on the lateral sides

Abstract

A buckling-restrained steel plate shear wall (BRSPSW) structure with butterfly-shaped links on the lateral sides is introduced to improve the cooperative performance between the BRSPSW and the boundary frames.A one-span two-story concrete-filled steel tube (CFT) column frame specimen equipped with lateral-side butterfly-shaped linked BRSPSWs (LBL-BRSPSWs) is evaluated under low-cycle reversed loading.A finite element (FE) model is developed and validated based on the test results.This FE model accurately simulates the failure modes and load-displacement curves.Parametric analyses are conducted on the butterfly-shaped links.The results show that the interactions between the CFT column frame and LBL-BRSPSWs are significantly influenced by the width ratio of the butterfly-shaped links, while the taper ratio and aspect ratio have relatively minor influences.Compared with traditional steel shear walls with four-sided connections, LBL-BRSPSWs reduce the additional axial forces and bending moments in the frame columns by 28% to 73% and 17% to 87%, respectively, with only a 9% to 30% decrease in the lateral resistance.The experimental and parametric analysis results indicate that setting butterfly-shaped links on the lateral sides of BRSPSWs can significantly enhance their cooperative performance with the boundary frame.The butterfly-shaped link width ratio has a linear relationship with the lateral-resistance performance of the specimens and the additional internal forces in the frame columns.To ensure that LBL-BRSPSW fails prior to the column frames, the link width ratio should be optimized.
