Fabricated steel frame and steel plate shear wall structure replaceable after earthquake

Abstract

The invention discloses a fabricated steel frame and steel plate shear wall structure replaceable after an earthquake. The fabricated steel frame and steel plate shear wall structure comprises frame steel columns, main steel beams, post-earthquake replaceable energy dissipating joints and post-earthquake replaceable embedded steel plates. Webs of column bodies of the frame steel columns are connected through first end plates. Second end plates of each main steel beam are fixedly arranged at the two ends of a corresponding beam body. Third end plates of each post-earthquake replaceable energy dissipating joint are fixedly arranged at the two ends of a corresponding beam section, and connected with the corresponding second end plate of the corresponding beam body and an inner flange of the corresponding column body through bolts correspondingly. The post-earthquake replaceable embedded steel plates are connected with the inner flanges of the corresponding column bodies and the corresponding beam bodies through bolts, and long grooves are formed in the portions, making contact with the corresponding post-earthquake replaceable energy dissipating joints, of the four corners of each post-earthquake replaceable embedded steel plate. Internal force can be effectively transmitted, and it is guaranteed that the structural integrity and stress performance are given to full play; and structural failure and a failure mechanism are actively controlled, it is guaranteed that a main body structure is kept in an elastic state, plastic energy dissipation and damage occur in designated local positions, post-earthquake replacement and repairing are facilitated, and economic loss is reduced.

Description

technical field [0001] The invention relates to the technical field of lateral force resistant structures, in particular to a replaceable assembled steel frame and steel plate shear wall structure after an earthquake. Background technique [0002] Based on the urgent need for the construction of high-rise and super high-rise buildings and the current situation of frequent strong earthquakes, steel frame and steel plate shear wall structures have developed rapidly in recent years as a structural system with excellent lateral resistance. Compared with the traditional steel frame system, it has larger initial lateral stiffness and higher shear bearing capacity after buckling; compared with the traditional steel frame and concrete shear wall system, its material is consistent, deformation is easy to coordinate, ductility It is easy to match, easy to connect and construct, and it can avoid the rapid decrease of the bearing capacity of the steel frame as the second line of defense...

Problems solved by technology

The traditional wall panel connection form is the welded connection between the wall panel and the fishplate, and the fishplate is welded to the frame beam and frame column. This welding connection means that after a strong earthquake, although the steel column and the main steel beam can still maintain elasticity, However, the damaged beam end joints, embedded steel plates and connectors cannot be replaced, resulting in huge economic losses and unable to meet the urgent need for rapid repair of lifeline projects. Therefore, a steel frame and steel plates that can replace the damaged position after the earthquake are proposed The shear wall structure system is very necessary
