摘　　要：对带支撑异形柱结构进行了三维非线性时程分析。比较了几种支撑设置方案的分析结果可知,对于文中算例,只在底部设支撑,不能满足抗震规范的要求。为确保结构安全,仍需通高设支撑。所得结论可作为带支撑异形柱结构设计的参考。Nonlinear time-history analysis for frame structure with special-shaped columns and bracings is carried out. The results of several bracing-setting schemes are compared. However, the seismic capability of the structure with bracing only at the first story can＇t meet the regulation of the seismic code. For the sake of safety, setting bracings along the whole height of the structure is necessary. The conclusions are helpful for seismic design of similar structures.
