摘　　要：通过对异形柱框架—剪力墙结构的工程实例及构建的矩形柱框架—剪力墙结构进行在地震作用下反应谱分析和弹塑性时程分析的对比,探讨了异形柱框架—剪力墙结构的动力特性。计算结果表明:异形柱框架—剪力墙结构与矩形柱框架—剪力墙结构的抗震能力基本相当,但在烈度较高的地区及结构平面不规则时,应考虑地震作用方向角的敏感性对结构的不利影响。The frame-shear wall structure with special-shaped columns and the frame-shear wall structure with rectangle columns are analyzed contrastively in this paper by response spectrum analysis and elastic-plastic time history analysis under earthquake action,then the dynamic characteristics of the frame-shear wall structure with special-shaped columns are studied.The results show that there is little difference in the earthquake resistant capability between the two structures,but the adverse effect of the sensitivity of the seismic direction angle on the structure should be taken into account under the conditions like high intensity seismic region and irregular plane structure.
