屈曲约束支撑体系的应用与研究进展(Ⅱ)
The Practice and Research Development of Buckling-Restrained Braced Frames(Ⅱ)
【摘要】 屈曲约束支撑框架体系(BRBF)是新近发明并逐渐得到应用的一种框架体系。因为屈曲约束支撑(BRB)在受拉和受压时都可屈服而不屈曲,因此克服了传统支撑体系的缺点。第二部分简要介绍了SEAOC-AISC提出的反复加载试验要求,介绍了BRB各组成部分、BRB构件本身及BRBF体系的性能,以及BRBF的设计方法。
【Abstract】 Buckling-restrained braced frame (BRBF) is a newly developed steel braced frame system for seismic resistance.Since buckling-restrained brace (BRB) can yield in both tension and compression without buckling,the disadvantages of the conventional braced frame system can be overcome.This paper is devoted to the behavior of BRBs at the component,the subassembly and the system levels.Testing requirements as well as seismic design procedures proposed by SEAOC-AISC are also presented.
