支撑—异形柱钢框架结构的静力弹塑性分析

Nonlinear static analysis of braced special-shaped column steel frames

简述了Push-over方法的基本原理,并运用ETABS对柱截面积相同、柱形(H形柱,异形柱)不同的支撑—钢框架结构进行弹塑性分析,发现了支撑—异形柱钢框架结构抗震性能优于纯钢框架结构,支撑—异形柱钢框架较支撑—H形柱钢框架弱侧抗侧能力更好等优点。

The basic principle of Push-over analysis method was stated,and using ETABS made nonlinear static analysis for braced steel frames,which had the same column area and the different type（H column,special-shaped column）.It is found that the seismic properties of braced steel frames are better than pure steel frame,wake side resistance capacity of braced special-shaped column steel frame is better than braced H column steel frame.
