Fabricated recycled concrete composite shear wall structure

Abstract

The invention provides a fabricated recycled concrete composite shear wall structure comprising a first pre-embedded body, a second pre-embedded body and a wall body. The first pre-embedded body and the second pre-embedded body are of U-shaped structures, the opening end of the second pre-embedded body is inversely buckled into an open slot of the first pre-embedded body, and a top plate of the second pre-embedded body is connected to the basic end of the wall body; one ends of connecting positions of the first pre-embedded body and the second pre-embedded body in hinged connection, and the other ends are slidably connected; and the hinged connection position and the sliding connection position are both provided with piezoelectric stacks, and the piezoelectric stacks are connected with a controller. In the fabricated recycled concrete composite shear wall structure, the controller is used for adjusting voltage applied to the piezoelectric stacks under different seismic load effects, the rotational friction and the sliding friction of a core region are adjusted, the purpose of self-adaption of the overall structure to seismic responses is achieved, and real-time variable-friction shear resistance under the small and medium seismic action is achieved; and under the rare occurrence earthquake effect, a large amount of seismic energy is consumed.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption of a shear wall structure, in particular to an assembled recycled concrete composite shear wall structure. Background technique [0002] In order to meet the increasingly diverse needs of architectural forms in modern society, the height and span of buildings continue to increase, so the coordinated development of structures and related design theories is required. The prefabricated structure has the advantages of fast construction speed, guaranteed component quality, and labor saving. It has been widely used in shopping malls, parking lots, middle and low-rise residences, hotels, etc. in New Zealand, Canada, Japan, and the United States. The specific structural types used include prefabricated frames, shear wall structures, and prefabricated prestressed structures. In order to adapt to the new situation of my country's economic development, prefabricated structure...

Problems solved by technology

At present, for the research on the horizontal connection method of the prefabricated shear wall, the typical methods adopted are "sleeve grouting, anchor grout lap, extrusion sleeve", etc., but these connection methods are still difficult to make the prefabricated shear wall structure The internal force transmission path and constraints at the horizontal joints are exactly the same as those of the cast-in-place shear wall structure
