摘要 为研究后加墙体的端柱-剪力墙在低周往复载荷作用下的破坏形态、承载力和延性等抗震性能,用Abaqus中新-老混凝土黏结界面的建模方法,对加固形成的端柱-剪力墙进行受力分析。结果表明:后加墙体的端柱-剪力墙与整浇剪力墙的抗震性能有一定差异,不宜直接按整浇结构计算刚度和抗震承载力。 In order to study the failure mode, bearing capacity and ductility of end column shear wall with post added wall under low cycle reciprocating load, the modeling method of bond interface between new and old concrete in Abaqus is used to analyze the stress of the reinforced end column shear wall. The results show that the seismic performance of the end column shear wall with the post added wall is different from that of the monolithic shear wall, and it is not suitable to calculate the stiffness and seismic bearing capacity directly according to the monolithic structure.
