| 摘 要： | 偏心支撑钢框架是近二十多年来发展起来的一种支撑结构形式，具有很好的抗震性能。为了更好地了解偏心支撑框架抗侧力性能和耗能梁段的受力特性，本文对偏心支撑钢框架进行非线性有限元分析。分析结果表明，偏心支撑中的耗能梁段在加载后期发生剪切屈服型破坏，保证了框架其他杆件不屈服，提高了结构的耗能能力和变形能力，显著地改善了钢框架的抗震性能。

| Abstract: | Eccentrically braced frame is one of new resistant-lateral systems in recent years and it has well resistant-seismic behavior. In order to study the its resistant seismic behavior and characteristic of link, nonlinear finite element analysis for eccentrically braced frame was performed in this paper. Analysis indicated that link of this frame yielded in the last loading and occurred cut mode failure and insure that the other components did not failed. So enhance the absorbs seismic energy and distortion capability, improved the resistant seismic behavior of frames. |
