摘要
防屈曲支撑作为一种新型消能构件,克服了传统支撑受压屈曲、无法充分发挥材料受压阶段的塑性滞回耗能功用的缺点,具有工作原理简单、明确、消能效果好等特点,是一种十分有应用前景的结构消能构件。本文主要介绍国内外防屈曲支撑的研究进展,重点从防屈曲支撑的工作原理与构成,其构件、组件、结构体系等层面进行论述。
As a new type of energy dissipation component,buckling-restrained brace overcomes traditional brace's drawbacks,such as compression buckling,inability to make full use of material's plastic hysteretic energy dissipation function when under pressure.Buckling-restrained brace also has the advantage of its simple working principle and high-efficiency energy dissipation function.It is a kind of very promising structure's energy dissipation component.This paper mainly introduces the research progress of buckling-restrained brace at home and abroad,focusing on BRB's working principle and composition,BRBF subassembly and BRBF system.
