Method for improving continuous earthquake disaster resistance of reinforced concrete structure

Abstract

A method for improving continuous earthquake disaster resistance of a reinforced concrete structure comprises the following steps that a, an SMA plastic hinge connector is made, an SMA connection rod is connected between two rebars, the rebars and the SMA connection rod are connected head to tail through a stainless steel sleeve, the stainless steel sleeve and one ends of the rebars are connected through taper threads, and the stainless steel sleeve and one end of the SMA connection rod are connected through a bolt fixedly in a compressed mode; b, the SMA plastic hinge connector is placed in a plastic hinge area of the reinforced concrete structure, and the plastic hinge area is determined through structural antiseismic calculation; and c, the SMA plastic hinge connector is fixed, then concrete is poured, and the reinforced concrete structure provided with the SMA plastic hinge connector in a embedded mode is constructed. Through the method, the antiseismic performance of the reinforced concrete structure under continuous earthquake disasters is improved.

Description

technical field [0001] The invention belongs to the field of architecture and civil engineering, in particular to a method for improving the resistance of reinforced concrete structures to continuous earthquake disasters. Background technique [0002] Reinforced concrete structure is the most widely used structural form in the field of civil engineering and plays an extremely important role. Although the steel bar has good strength, stiffness, ductility and applicability, it will produce large residual deformation after the earthquake, and the residual deformation will continue to accumulate under the action of continuous earthquake disasters, resulting in the gradual degradation of the seismic performance of the structure and even collapse. , so that the functionality of the structure after the earthquake cannot be guaranteed, and a large maintenance and restoration cost is required. Therefore, improving the ability of reinforced concrete structures to resist continuous ea...
