带多块混凝土板的防屈曲钢板剪力墙边缘柱内力需求计算分析
In ternal forces demand calculation of boundary columns of buckling-restrained steel plate shear wall with multi-concrete panels
摘要
Abstract
Small cross-sections of boundary elements easily induce the"internal tension"phenomenon of steel plate shear walls,making it difficult to fully utilize the seismic performance of buckling-restrained steel plate shear walls.The design of cross-sections of boundary elements is related to their internal force requirements,and analyzing the internal force requirements of boundary columns is meaningful.Based on the proposed buckling-restrained steel plate shear wall with multi-concrete panels(MBRSPSW),the analytical expressions for the internal force of the boundary column of the MBRSPSW were theoretically derived in this paper.Combined with the experimental research on the buckling-restrained steel plate shear wall horizontally assembled multi-concrete panels(H-MBRSPSW),its numerical model was established and verified.The internal force distributions of the boundary column obtained from numerical analysis and analytical calculation were further compared.The research results indicate that the inner steel plates in the MBRSPSW are divided into constrained regions and unconstrained regions.The axial force,shear force,and bending moment distributions of the boundary column from the analytical calculation results agree with those from the numerical analysis results,and the internal force calculation expressions of the boundary column are correct.The research results can provide a reference for the design of this category of steel plate shear walls.关键词
