Self-resetting reinforced concrete shear wall

Abstract

The invention discloses a self-resetting reinforced concrete shear wall and relates to the technical field of shear walls. Including: the foundation shear wall, the prefabricated shear wall connected to the foundation shear wall through the first shear connector, and a number of reset components respectively arranged on both sides of the prefabricated shear wall, and at least A reset assembly, the reset assembly includes a cylinder, a piston rod slidably connected to the cylinder, a disc spring set mounted on the piston rod, and a number of metal rings sleeved on the piston rod, one of the cylinder and the piston rod is used One is used to connect with the foundation shear wall, and the other is used to connect with the prefabricated shear wall. In this way, the first shear connector can bear the horizontal loads on the prefabricated shear walls caused by earthquakes and strong winds, and can utilize the energy dissipation capacity and deformation recoverability of the superelastic shape memory alloy ring spring to achieve the purpose of dissipating earthquakes. The effect of energy and post-earthquake structure self-resetting greatly reduces the difficulty and cost of post-earthquake repairs.

Description

technical field [0001] The invention relates to the technical field of shear walls, in particular to a self-resetting reinforced concrete shear wall. Background technique [0002] In the high-rise building structure, the reinforced concrete shear wall is the main anti-lateral force component, which has the advantages of good integrity, high lateral stiffness, high bearing capacity, good seismic performance, and flexible layout. At the same time, the arrangement of shear walls can avoid problems such as exposed beams and exposed columns caused by inconsistent widths of beams and columns in residential buildings when using frame structures. In particular, the shear wall structure system avoids a series of construction difficulties such as setting supports in the frame structure, supporting after opening, and filling walls. In recent years, the industrialization of construction has gradually replaced traditional construction methods, and the structural adjustment and technolog...

Problems solved by technology

This method relies on the prestress and the self-weight of the structure to realize the self-resetting of the shear wall structure under the action of lateral loads such as earthquakes. It is often difficult to control the swing amplitude of the structure when it sways, causing the overall overturning of the shear wall. In addition, When subjected to large earthquakes, this type of shear wall structure has insufficient ability to consume seismic energy, which often leads to cumulative damage to the concrete at the root of the shear wall due to repeated collisions, making it difficult to repair and replace components.
