建筑抗震构件中屈曲约束支撑结构研究新进展

Recent Progress in Buckling-Restrained Brace Structures as Seismic Components of Buildings

摘要:

详细介绍了近年来中国学者在屈曲约束支撑研究方面取得的研究成果，着重讨论了屈曲约束支撑构件（核心单元、约束机构、无黏结构造层）和整体抗震性能以及设计方法的研究现状。结果表明：屈曲约束支撑以其良好的耗能性能具有很好的发展潜力，屈曲约束支撑的适用范围不断拓展，结构形式更趋多样化，设计方法不断优化。

Abstract:

This paper introduces the research results of buckling-restrained braces (BRBs) in recent years in China and focuses on the research status of BRB members (core element, restraint mechanism, cohesionless layer), overall seismic performance, and design methods. Based on the review, the following is concluded: the BRB has a good development potential because of its good energy-dissipation performance; the application scope of the BRB is expanding; the structural forms are becoming more diversified; and the design methods are constantly being optimized.
