The working mechanism of the shear wall with the shock-absorbing structure and the recoverable function of the utility model will be explained below.

When earthquake occurs, when the earthquake acting force applied to the wall body structure of the shear wall is larger than the initial static friction force between the wave curved surfaces of the upper wall wave plate and the lower wall wave plate of the shock absorption structure, the wall body begins to swing under the action of the earthquake; at the moment, energy consumption is carried out through the friction action between the wave curved surfaces of the upper wall wave plate and the lower wall wave plate of the shock absorption structure, so that the shock absorption of the wall body structure is realized; because the diameters of the bolt holes of the energy consumption plate 4, the upper wall corrugated plate, the lower wall corrugated plate and the transition block are larger than the outer diameter of the high-strength bolt, the high-strength bolt slides in the bolt hole, the upper wall corrugated plate and the lower wall corrugated plate are dislocated, the belleville spring on the outer side of the energy consumption plate 4 is extruded, and the energy consumption capability and the anti-seismic performance of the damping structure are further improved. Before the high-strength bolt slides to the edge of the bolt hole, the wall structure consumes energy mainly through the friction between the wavy curved surfaces and the elasticity of the belleville spring; along with the enhancement of earthquake action, high strength bolt slides to the edge of bolt hole, and energy consumption board 4 begins to play a role, dissipates the seismic energy through tensile deformation.

After the earthquake action is finished, the shear wall is restored to the original position through the self-resetting capability of the prestressed tendons 2 and the self weight of the wall body, so that the normal use of the building after the earthquake is realized. And, in the process of the building structure suffering from earthquake action, the prestressed tendons 2 can also be cooperated to dissipate earthquake energy.

After the earthquake action is finished, if the shock absorption structure in the shear wall is damaged in the earthquake, the structure and the function of the shear wall can be recovered by replacing the shock absorption structure or replacing part of elements of the shock absorption structure.

the diameters of the bolt holes in the transition block, the upper wall corrugated plate, the lower wall corrugated plate and the energy dissipation plate 4 are 4-6 mm larger than the outer diameter of the high-strength bolt, so that the high-strength bolt can slide in the hole.
