Problems solved by technology

Under normal use conditions and frequent earthquakes, the traditional buckling-restrained bracing only uses the axial stiffness of the core plate and does not use the axial stiffness of the external restraint members, so the improvement of the lateral stiffness of the structure is small

Abstract

The invention discloses a variable rigidity buckling-restrained brace containing lead core materials. The variable rigidity buckling-restrained brace comprises a core plate, stiffened ribs, stiffened rib plates, filling materials, steel plates with grooves, external restraining members, the lead core materials and a jacking device. The external restraining members are arranged on the periphery of the core plate. The filling materials are arranged between the core plate and the external restraining members. Spaces between the filling materials and the core plate are coated with unbounded materials. The stiffened ribs are arranged on the upper and lower sides of the two ends of the core plate, and the stiffened rib plates are fixed on the upper portions of the stiffened ribs. The steel plates with the grooves are fixed inside the external restraining members and correspond to the stiffened rib plates in position. The stiffened rib plates make close contact with the steel plates with the grooves. Grooves with the positions being completely overlapped are formed in the upper surfaces of the stiffened rib plates and the lower surfaces of the steel plates with the grooves. The lead core materials are placed between the two steel plate grooves. Holes are formed in the same positions of the stiffened rib plates, the steel plates with grooves and the external restraining members. One end of the jacking device is placed in the formed holes and the other end of the jacking device is placed on the core plate. Construction is convenient, and replacing is facilitated.

Description

technical field [0001] The invention relates to a buckling-constrained support with variable stiffness of a lead-containing material, belonging to the technical field of anti-seismic and energy-dissipating shock-absorbing engineering structures. Background technique [0002] The traditional method to improve the earthquake resistance of buildings and structures is to optimize the structural system, and to enhance the strength, stiffness and ductility of the structural members themselves by adjusting the size of the members, reinforcement, etc. to resist the earthquake and dissipate the input energy of the earthquake. The anti-seismic performance of the measures is limited, which affects the overall layout of the structure, and the structural system will be damaged under the action of the earthquake, resulting in a large post-earthquake repair cost. [0003] With the development of structural shock absorption technology, shock absorbers are being widely used. The principle is...
