屈曲约束支撑研究进展综述

Review on the development of buckling-restrained braced

本文旨在对屈曲约束支撑做一个综合性分析。文章从两方面展开对国内外近几年在屈曲约束支撑方面的研究成果的分析总结。一方面是此种支撑受力机理的研究,另一方面是新型支撑形式的介绍。同时对于此种支撑形式在一般通用软件的建模做了简要介绍,并对目前仍不能在国内广泛应用做了原因分析。

This article is aimed at make a comprehensive analysis on the buckling - restrained braced. The paper summarized the research of BRB in recent years both at home and abroad. The stress mechanism of such brace has been studied at first, and then some new forms of such braces are intro- duced. And modeling in different common software also been given. At last, analyzed reasons of not been able to used widely in our country. All of the work is hoping to make a tull understanding of the new form of brace for the engineers.
