Function-recoverable coupled shear wall based building anti-seismic structure and construction method

Abstract

The invention relates to a function-recoverable coupled shear wall-based building anti-seismic structure and discloses a construction method thereof. The anti-seismic structure comprises function-recoverable coupled shear walls and floor plates, wherein the function-recoverable coupled shear walls are provided with replaceable connecting beams and steel-pipe concrete supporting seats, and the floor plates are connected with the coupled shear walls through connecting members; replaceable members are arranged at middle parts of the replaceable connecting beams, concrete is excavated out from wall footing, pre-stressed bars and the steel-pipe concrete supporting seats are arranged at the wall footing, slots are formed in the floor plates at positions of the coupled shear walls, and connecting members with high tension and compression and low shear torsion are connected with the coupled shear walls. According to the function-recoverable coupled shear wall based building anti-seismic structure and the construction method, the energy consumption characteristic of the replaceable members can be effectively exerted, and the damage to the wall footing and the floor plates is avoided, so that the damage to the coupled shear walls of the structure is only focused on the replaceable members of the connecting beams, the damage is controllable during quaking, and functions of the replaceable members can be recovered after quaking; the structure is high in sustainable earthquake resistance and low in full-life cost, can be extensively applied to the field of earthquake resistance of structures and has a good application prospect and economic technical benefits.

Description

technical field [0001] The invention belongs to the field of anti-seismic technology of structural engineering, and relates to a recoverable function technology applied to a combined shear wall, in particular to an anti-seismic structure and construction method of a house based on a recoverable function combined shear wall. Background technique [0002] The recoverable functional structure can meet the new demand for sustainable earthquake resistance of the structure, so that the structure has the ability to quickly recover after the earthquake while resisting the earthquake disaster, improve the efficiency of disaster relief after the earthquake, and reduce the loss of earthquake damage. As a widely used structural lateral force-resisting component, the realization of the recoverable function of the combined shear wall in the structure is the premise of the wide application of the recoverable function structure. At present, the main measure is to set up replaceable connectin...

Problems solved by technology

Therefore, even if the damaged coupling beam fuse is replaced after the earthquake, the entire structure cannot be restored to its original state due to the damage to the foot of the shear wall cannot be eliminated

[0004] As mentioned above, the damage of the combined shear wall with replaceable coupling beams is not completely concentrated on the replaceable components of the coupling beams, and the foot of the wall is still damaged. In addition, the transverse members connected with the coupled shear walls in the structure The floor will limit the deformation of the replaceable components, and the shear force transmitted to the floor will also easily damage the floor. The ability of the replaceable components to shear energy and concentrate plasticity is hindered, and the recoverability of the combined shear wall in the structure cannot be truly realized.
