摘　　要：防压曲支撑作为一种新型的耗能减震构件,抑制了普通的支撑的压曲现象,能更多地吸收和耗散地震输入给结构的能量,提高了框架的抗震性能和能力。框架-防压曲支撑体系目前在美国、日本和中国台湾地区应用比较广泛,在中国大陆的工程应用较少。讨论了防压曲支撑的构造技术,介绍了防压曲支撑的研究与应用现状,展望了应用前景并提出了若干意见。The Buckling-Restrained Brace （BRB） is superior to traditional brace because of its buckling inhabitation and good energy dissipation ability as well as ductility during earthquake. The BRB Frame （BRBF）has been comparatively widely used as a new type of energy dissipation and seismic mitigation component in USA, Japan and Chinse Taiwan, etc. It has been used little in mainland, China. The composition of the BRB is analyzed.The state of art of the current research and engineering application of the BRB and BRBF at home and abroad are outlined ,and has made some suggestion.
