Prestress cable-strut type buckling-restrained brace
The invention relates to a prestress cable-strut type buckling-restrained brace, and belongs to the technical field of structural engineering. The prestress cable-strut type buckling-restrained brace comprises a crossed core component and a periphery constraint component. The crossed core component is formed by welding three flat steel plates, and hard rubber is attached to the surface of the crossed core component. The periphery constraint component is composed of steel tube concrete and a prestress cable-strut system. The end of a prestress confining part is fixed to a steel cable head of a brace end socket, and the middle of the brace is supported through a circular steel plate. According to the prestress cable-strut type buckling-restrained brace, by means of the cable-strut system formed by the tensioned prestress inhaul cable and the circular steel plate, effectively lateral elastic supporting points are provided for the steel tube concrete, and overall elastic buckling load and the restraining ratio of the steel tube concrete are increased, so that the section size of the periphery constraint steel tube concrete is as small as possible and a core is fully constrained; the section size of the periphery constraint steel tube concrete is reduced through the periphery cable-strut system, the overall self-weight of the components is reduced, and the components are convenient to transport; the components are more attractive in appearance.
