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.
