Reinforced concrete mixed shear wall with replaceable earthquake damaged part

Abstract

The invention discloses a reinforced concrete mixed shear wall with a replaceable earthquake damaged part. A reinforced concrete shear wall and a concrete base are mutually hinged through an upper lug plate and a lower lug plate and form a support by concrete short columns, the bottoms of the concrete short columns are locked inside the concrete base through long bolts, the concrete short columns are provided with reinforcement supporting frameworks, the outsides of the concrete short columns are prepared by casting concrete, the reinforcement supporting frameworks comprise longitudinal force bearing reinforcements and transverse force bearing reinforcements, the longitudinal force bearing reinforcements are vertically arranged, the transverse force bearing reinforcements are diverged from axes of the concrete short columns to the outsides, and the longitudinal force bearing reinforcements and the transverse force bearing reinforcements are mutually welded. After a wall body is damaged by an earthquake, rapid maintenance and reconstruction are realized by replacing the concrete short columns, and the reinforced concrete mixed shear wall has good reusability and is more economical and practical.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a reinforced concrete hybrid shear wall with replaceable earthquake-damaged parts. Background technique [0002] The anti-seismic thinking in my country at the present stage is "not damaged by small earthquakes, repairable by moderate earthquakes, and not collapsed by major earthquakes". This anti-seismic idea requires that the main structure should not be damaged and can be repaired after the structure encounters an earthquake with fortification intensity. However, due to the uncertainty and complexity of the seismic action, the structure may suffer from an earthquake with a greater intensity than the fortification, which will seriously damage the structural components. In addition, although the structure may not collapse after being subjected to an earthquake of fortification intensity, some components cannot be repaired due to excessive residual deformation. In th...

Problems solved by technology

However, due to the uncertainty and complexity of the seismic action, the structure may suffer from an earthquake with a greater intensity than the fortification, which will seriously damage the structural components.

In addition, although the structure may not collapse after being subjected to an earthquake of fortification intensity, some components cannot be repaired due to excessive residual deformation. In the end, the entire structure can only be demolished and rebuilt, resulting in huge waste and affecting people's normal life.
