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。
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 ~entrically 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.
