Truss-restrained type buckling-restrained brace
The invention relates to a truss-restrained type buckling-restrained brace and belongs to the technical field of structural engineering. The buckling-restrained brace comprises a cross-shaped core steel member and a peripheral restrained member. The cross-shaped core steel member is formed by welding three flat steel plates, and hard rubber is adhered on the surface of the cross-shaped core steel member. The peripheral restrained member consists of a confined concrete-filled steel tube, two bent square steel tubes and connecting square steel tubes. Each bent square steel tube is formed by connecting two short straight square steel tubes with a long straight square steel tube, the two bent square steel tubes are placed at the symmetric positions on two sides of the confined concrete-filled steel tube and are equal in distance from the confined concrete-filled steel tube within a middle long area, and the positions, close to the ends of the peripheral restrained member, of the bent square steel tubes bend and are connected with the confined concrete-filled steel tubes by welding at the ends of the peripheral restrained member. The connecting square steel tubes are arranged obliquely in pairs in the length direction of the peripheral restrained member, and two ends of each connecting square steel tube are welded with the corresponding bent square steel tube and the confined concrete-filled steel tube respectively. The truss-restrained type buckling-restrained brace can be used as super-tonnage buckling-restrained braces crossing multiple storeys in a high-rise structure, and the members are more attractive in appearance.
