Study on Design of Connection Between Buckling-Restrained Brace and Frame Joint
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.
