[摘要] 某双塔连体结构中分别采用普通钢支撑与屈曲约束支撑两种支撑方式,运用SAP2000软件分别对两种支撑方式在大震作用下进行动力弹塑性时程分析;并对计算结果中的楼层剪力、层间位移角、顶点位移及整体塑性发展做出分析比较,得出屈曲约束支撑对刚度突变及抗剪承载力突变有一定的控制作用。

Abstract: The common steel braces and buckling restrained braces were used in a connected double-towers structure. Finite element software SAP2000 was used to carry out dynamic elastic-plastic time-history analysis on two types of braces under the rare earthquake. The results are compared such as the story shear, story drift, top displacement and the overall plastic deformation development. Through calculation, it’s concluded that the buckling restrained braces have some effects in controlling stiffness mutation and story shear mutation.
Keywords: connected structure; steel brace; buckling restrained brace; dynamic elastic-plastic time-history analysis
