Damping infilled wall of RC frame structure and manufacturing method of damping infilled wall

Abstract

The invention provides a damping infilled wall of an RC frame structure and a manufacturing method of the damping infilled wall. The structure comprises a masonry structure which is defined by frame columns and frame beams and arranged in space in a masonry manner. Column inner side steel plates are mounted on the inner sides of the frame columns of the masonry structure. Multiple transverse steelbars are welded between the two column inner side steel plates. A bottom-layer wall body, a first-layer H-shaped sliding rail, a middle-layer wall body, a second-layer H-shaped sliding rail and a top-layer wall body are sequentially arranged on the frame beam at the bottom in a masonry manner. Plane outer protection steel plates are mounted on the front portions and the rear portions of the contact positions of the bottom-layer wall body, the middle-layer wall body and the top-layer wall body with the column inner side steel plates. The problems that an existing masonry infilled wall suffersfrom brittle failures under the reciprocation loading function and collapses, stress redistribution is caused, and brittle failures happen to the frame structure are solved; and the novel damping infilled wall of the RC frame structure is provided, and the ductile failure form of the infilled wall and an RC frame is achieved so as to avoid collapsing of the infilled wall and brittle failures, caused by damage of the infilled wall, of an RC frame body.

Description

technical field [0001] The invention relates to a shock-absorbing filling wall of an RC frame structure, belonging to the technical field of building materials. Background technique [0002] In the past two decades, the rapid development of my country's construction industry has greatly stimulated the domestic economy. However, after the Wenchuan earthquake, a large number of earthquake damage analyzes showed that the most widely used reinforced concrete structure with infill walls has many problems in its seismic performance, such as the phenomenon of strong beams and weak columns due to the unreasonable design of the reinforcement ratio of beams and columns, and the infill walls The brittle failure and even collapse of the concrete frame caused by the restraint of reinforced concrete, the short column effect caused by the uneven restraint of the column after the infill wall is opened, the column is damaged at the window edge, the casualties caused by the collapse of the in...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of brittle failure of the existing masonry infill wall under the action of reciprocating load, self-collapse and stress redistribution, resulting in brittle failure of the frame structure, so it provides a novel RC frame structure Infill wall, the internal displacement of the infill wall under the earthquake is concentrated in the slide rail layer of the shock-absorbing infill wall to realize the ductile failure form of the infill wall and the RC frame to prevent the collapse of the infill wall and the main body of the RC frame due to the failure of the infill wall Brittle failure
