摘　　要：防屈曲支撑通过特殊的构造,避免了中心支撑受压屈曲的问题,在受拉和受压时均可屈服而不屈曲,能更好地消耗输入结构的地震能量,近年来在国内外的应用和研究逐渐增多。简要介绍了防屈曲支撑的研究进展和应用,并探讨了防屈曲支撑的设计要点,给出了防屈曲支撑杆件的计算和构造要求。　Buckling-restrained braces can yield under both tension and compression without buckling to avoid the disadvantages of center brace for better energy dissipation.There are more and more research and application projects about buckling-restrained braces at home and aboard.This paper is devoted to the development and application of buckling-restrained braces and discussing the design points of buckling-restrained braces.The calculation and construction requirements are also presented in this paper.

关 键 词：防屈曲支撑 钢框架 耗能 减震
