| 摘 要： | 近年来，我国的大中城市相继出现了大批的中高层钢结构建筑。框架一支撑结构体系作为中高层的一种结构形式被广泛采用。本文运用大型通用有限元软件ANSYS，采用三维建模，对-9层框架-支撑钢结构建筑进行了抗震性能的计算分析，分析包括模态分析、反应谱分析、弹性刀单塑性时程分析，分析结构在地震作用下的横向变形和支撑随地震波的内力响应情况等。研究成果可以为类似工程提供借鉴。

| Abstract: | Steel braced frame is one of the structure forms in mid-high rise building widely used. In the paper, a certain 9 storey braced frame in langfang is designed as an example through the finite element software ANSYS. Three-dimensional modal is built, and the seismic response is analyzed including modal analysis, response spectrum analysis,elastic/elastoplastic time-history analysis. The lateral deformation of the structure and the stress of the braces are computed, and the study can be served as the references of such structure design. |
