Self-resetting repairable energy dissipation shear wall

Abstract

The invention relates to the technical field of civil engineering structures, in particular to a self-resetting repairable energy dissipation shear wall. The self-resetting repairable energy dissipation shear wall comprises a shear wall main body and a self-resetting repairable energy dissipation assembly, wherein the self-resetting repairable energy dissipation assembly is fixedly connected withthe shear wall main body, and the self-resetting repairable energy dissipation assembly is a bearing capacity energy dissipation component. The self-resetting repairable energy dissipation assembly isfixedly connected with the shear wall main body, the self-resetting repairable energy dissipation assembly is the bearing capacity energy dissipation component so that the self-resetting repairable energy dissipation assembly can dissipate energy of an earthquake input structure during an earthquake, the earthquake response of a building is reduced, after the earthquake, self-resetting can be achieved, structural residual displacement is reduced, the self-resetting repairable energy dissipation assembly can be rapidly repaired after the earthquake, and structural maintenance difficulty and maintenance cost are reduced.

Technical field[0001]The invention relates to the technical field of civil engineering structures, and more specifically, to a self-resetting and repairable energy-consuming shear wall.Background technique[0002]Earthquake disasters have the characteristics of unpredictability and strong destructive power. They have caused huge economic losses in the past and seriously threatened people's lives. At the same time, the reciprocating action of seismic forces will bring irreparable damage to buildings.[0003]Ordinary reinforced concrete shear wall structure is a lateral force resistance system widely used in multi-story and high-rise buildings. However, due to the rigidity of shear wall components, ordinary reinforced concrete shear wall components may undergo irreparable damage under earthquake action. Especially the wall toe at the bottom of the shear wall is prone to serious damage due to the huge overturning moment, and the maintenance is extremely difficult. In addition, damage to th...

Problems solved by technology

However, due to the high stiffness of the shear wall components, the ordinary reinforced concrete shear wall components may be irreparably damaged under the action of an earthquake.

Especially at the toe of the wall at the bottom of the shear wall, due to the huge overturning moment, it is prone to serious damage and is extremely difficult to maintain

In addition, the damage of shear wall components after the earthquake may cause large residual displacement of the structure, seriously affect the use of buildings, and cause huge direct or indirect economic losses
