Abstract

The invention discloses a variable stiffness buckling constraint support of a lead-containing material, which comprises a core plate, a stiffening rib, a stiffening rib plate, a filling material, a steel plate with grooves, an external restraining member, a lead core material, a jacking device, and a core An external restraint member is arranged on the periphery of the board, a filler material is arranged between the core board and the outer restraint member, a non-adhesive material is coated between the filler material and the core board, stiffeners are arranged on both ends of the core board, and the upper part of the stiffener is fixed The steel plate with grooves is fixed inside the external restraint member, and its position corresponds to the position of the stiffener plate. The stiffener plate and the steel plate with grooves are in close contact. On the upper surface of the stiffener plate and the lower surface of the steel plate with grooves There are grooves with completely overlapping positions, lead material is placed between the grooves of the two steel plates, the stiffener plate, the steel plate with grooves and the external restraint member are opened at the same position, and one end of the jacking device is placed in the opening , and the other end is placed on the core board. The invention is convenient in construction and easy to replace.

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...
