Abstract

Abstract: This paper research the optimal scope of width-to-thickness ratio α 1 of connection steel plate (CSP), thickness ratio α 2 between CSP and inner steel plates (ISP), and width-to-thickness ratio α 3 between the width of CSP and the thickness of the ISP of modular fabricated two-side connected buckling-restrained steel plate (MTBSP) shear wall. The finite element model (FEM) of the MTBSP shear wall is established based on the ABAQUS platform, which, considering the plastic-damage constitutive model of both concrete and steel materials. Through the result of a comparison between the test and FEM, it can be concluded that the FEM can effectively reflect the mechanical behavior of the MTBSP shear wall. Based on the verified FEM, the mechanical behavior of 93 computational cases with different ratios of α 1, α 2, and α 3 of MTBSP shear wall is investigated and the corresponding optimal scope of α 1, α 2, and α 3 are explored in detail. The results show that the mechanical performance of the MTBSP shear wall can be ensured effectively when the ratio α 1, α 2, and α 3 is in the scope from 10 to 20, from 3 to 5, and from 60 to 80, respectively. Research of this study can be provided supporting the reliable design of the MTBSP shear wall.
