[ 摘要] 中高层住宅由于经济效益好,设计人性化而受到了用户和开发者的重视,近年来,钢结
构以其自重轻、延性好、施工快等优势在中高层建筑中得到了广泛的运用。本文运用有限
元软件 ANSYS 对一特定的 9 层的钢框架-支撑结构进行计算分析,介绍了框架结构有限
元建模技巧,分析框架支撑结构的地震作用下的动力性能,并用 APDL 语言编程进行后
处理的简化。

[ Abstract ] Mid-high rise buildings are popular among residents and estate businessmen
because of their good economic benefit and humanization. Recently, steel structure is
widely used as one form of mid-high rise structures as it has many remarkable aspects
such as light deadweight, good ductility and quick construction. In the paper, the
dynamic properties of a certain 9 floor steel structure will be analyzed through the finite
element software ANSYS. The skill of modal building will be introduced in detail and the
seismic response of such kind of structure is analyzed. The postprocessing will be
simplified by APDL.

1 前言
中高层住宅(一般 7 层~10 层最为经济),因其与多、高层比较具有诸多优势,
既能适应现代居住生活要求、适合居民意愿,又可在一定程度上提高土地利用率、节约
土地资源,因而是大中城市住宅发展的必然趋势。
目前,中高层住宅的建筑材料主要是混凝土和钢材,相比较而言,混凝土结构运用
较多,技术比较成熟,而钢结构运用还不多,但是这
