| 摘 要： | 本文首先介绍了屈曲约束支撑(BRB)的最新研究进展。屈曲约束支撑在承受拉力和压力的情况下,表现出相同的滞回性能和优良的耗能能力。文章介绍了近些年来发展和应用比较成熟的一些形式的屈曲约束支撑。对于近些年来这种支撑在一些主要抗震地区的应用进行了回顾。对于新建高层钢结构的大量应用案例和已有结构的抗震加固的应用表明,此种支撑的使用前景非常广阔。

| Abstract: | This paper firstly presents a summary of buckling-restrained braces(BRBs).BRBs show the same load-deformation behavior in both compression and tension and higher energy absorption capacity.Research and developments of the various types of BRBs with different configurations are reviewed. Applications for both new high-rise steel buildings and the seismic retrofitting of existing buildings show good prospects of using BRBs. |
