| 摘 要： | V型偏心支撑钢框架具有很好的抗震性能。为了更好地了解V型偏心支撑框架抗侧力性能和耗能梁段的受力特性,本文针对V型偏心支撑钢框架进行非线性有限元分析。分析结果表明,V型偏心支撑的耗能梁段在加载后期发生剪切屈服型破坏,保证了钢框架其它杆件仍处于弹性,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: | V-TYPE eccentrically braced frame has well resistant-seismic behavior.In order to study the resistant seismic behavior and characteristic of link,nonlinear finite element analysis for V-TYPE 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. |
