Reinforced concrete hybrid shear wall with self-reset function

Abstract

The invention discloses a reinforced concrete hybrid shear wall with a self-reset function, wherein the reinforced concrete shear wall is in hinged connection with a concrete base by an upper lug plate and a lower lug plate, and supporting is formed by a concrete short pillar; and a perforative through hole is disposed vertically inside the concrete short pillar, a prestress rib passes through the through hole, and an I-shaped horizontal beam and a baseplate are clamped and pressed against on two ends of the concrete short pillars by the prestress rib. The invention provides the reinforced concrete hybrid shear wall with the self-reset function, wherein a wall body is not damaged easily in earthquake disasters because of elastic deformation resetting of the prestress rib, so that quake resistance of the wall body is greatly enhanced; structure requirements for ductility and energy consumption are fully satisfied; and the shear wall is more economic and practical.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a reinforced concrete composite shear wall with self-resetting function. 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 the end, the...

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.
