| 摘 要： | 偏心支撑框架与纯框架相比,有更大的抗侧移刚度及极限承载力,与中心支撑框架相比,可有效地降低地震作用.国内外学者对偏心支撑性能做了较多研究,但实际工程中鲜有应用,我国现有钢结构建筑大多为中心支撑框架或纯框架,结合一工程实例,对高层偏心支撑钢框架进行弹塑性时程分析和抗震性能研究.

| Abstract: | Eccentrically braced frames have larger lateral force resistance rigidity to unbraced frames and can effectively reduce the earthquake effect to centrically braced frames.Quite a few study of eccentrically braced frames has been given,but has seldom been put into practice.Which at present,in steel structure,is mostly centrically braced frames or unbraced frames.With a practical example,elastoplastic time-history analysis and the seismic performance of the high-rise eccentrically structure was accomplished. |
