A self-resetting shear wall with optimized stress distribution

Abstract

The invention belongs to the technical field of building structures, and relates to a self-resetting shear wall capable of optimizing stress distribution. The self-resetting shear wall comprises a reinforced concrete wall panel, a first force transmitting device, a second force transmitting device, a first flexible backing plate and a second flexible backing plate. The first force transmitting device and the second force transmitting device are separately arranged on two sides of the reinforced concrete wall panel. The lower end of the first force transmitting device penetrates through the first flexible backing plate, the lower end of the second force transmitting device penetrates through the second flexible backing plate, and the lower end of the first force transmitting device and thelower end of the second force transmitting device are both embedded in a reinforced concrete foundation beam. When a wall body of the shear wall is deformed, concrete of the foot of the wall is not prone to being plastically fractured; the overall stress level is evenly distributed, and materials are fully utilized; no obvious damage accumulation exists in reciprocating deformation, and no residual displacement occurs; the yield displacement is shifted backward; a plastic energy dissipation region is wide, and high ductility is achieved; a lateral deformation elastic stroke is large; the resetting ability is achieved; the out-of-plane stability is higher; and no additional internal force is applied to a wallboard.

Description

technical field [0001] The invention belongs to the technical field of building structures, and relates to a self-resetting shear wall capable of optimizing stress distribution, in particular to a self-resetting shear wall that realizes the wall reset target by optimizing the overall stress level distribution of the wall board, especially The utility model relates to a reinforced concrete shear wall with resetting ability comprising concrete, steel bars, steel pipes, steel rods and rubber pads. Background technique [0002] Earthquake is a natural disaster with strong destructive power, which can easily cause damage and collapse of buildings (structures), damage to equipment and facilities, interruption of traffic and communication, and damage to other lifeline engineering facilities. The damaged building structure requires long-term and high-cost repairs to restore the structural use function, which brings great economic losses to human society. In recent years, the design...

Problems solved by technology

[0004] The present invention solves the problem that when the traditional concrete shear wall and steel-reinforced concrete shear wall are deformed, the foot of the wall on both sides is easily crushed, the ductility is poor, and the residual deformation of the wall is large. The vertical bearing capacity of the prestressed self-resetting concrete shear wall is not high, and the side Due to the problems of large longitudinal deformation and easy loss of prestress, low vertical bearing capacity of replaceable foot shear walls, large residual deformation, and easy transfer of plastic zones, a self-resetting shear wall with optimized stress distribution was proposed.
