摘 要： 防屈曲耗能支撑作为一种新型的消能减震元件， 已被广泛、成功地应用于既有框架结构的抗震加固中。为使结构在地震作用下表现出良好的抗震效果，需保证防屈曲钢支撑与框架具备优良的协同工作性能， 因此支撑与框架之间的连接性能尤为重要。防屈曲钢支撑与框架节点之间的连接方法有焊缝连接、螺栓连接以及销轴连接。通过对节点板－框架连接处和节点板－支撑连接处进行受力分析，破坏形态分析，完善了加支撑框架节点处的计算公式。

Abstract : As a new energy consumption components , Buckling - Restrained Brace has been widely and successfully applied to the seismic strengthening of frame structure. To make the structure under seismic excitation showed good seismic behavior , excellent performance of collaborative work between Buckling - Restrained Brace and frame structure should been guaranteed , hence the connection performance of the two should been take seriously. Weld - connection , bolt - connection and pin - connection are common connection methods between Buckling - Restrained Brace and frame structure. In this paper , through the force analysis and failure mode analysis of joint plate - frame and joint plate - brace , the calculation formula of joint of braced frame is improved. 

Keywords : Buckling - Restrained Brace; frame structure; collaborative work; connection performance; connection methods
