Encased concrete composite shear wall embedded with dense steel plate beams between concrete-filled steel tube columns and construction method thereof

Abstract

An encased concrete composite shear wall embedded with dense steel plate beams between concrete-filled steel tube columns and a construction method thereof belong to the field of steel-concrete composite shear walls. The encased concrete composite shear wall is composed of concrete-filled steel tube frame columns, concrete-filled steel tube core columns, dense steel plate beams and a reinforced concrete shear wall with an I-shaped wall section. The encased concrete composite shear wall embedded with dense steel plate beams between concrete-filled steel tube columns is formed by the following steps that the concrete-filled steel tube frame columns are arranged at both ends of the reinforced concrete shear wall; the concrete-filled steel tube core columns are arranged between the concrete-filled steel tube frame columns; the level parallel dense steel plate beams are arranged between the concrete-filled steel tube frame columns and the concrete-filled steel tube core columns and between the concrete-filled steel tube core columns along the height direction of the reinforced concrete shear wall; the dense steel plate beams pass through the concrete-filled steel tube columns to be welded with steel tubes on intersection lines; shear wall reinforcing steel bars are bound; and concrete is poured. The encased concrete composite shear wall has the advantages that the bearing capability is enhanced, the ductility and the energy dissipation of the shear wall are enhanced due to multi-defenses, and the earthquake resistant capability is excellent. The encased concrete composite shear wall also has the advantages of convenience in construction and easiness in operation, and can be used in high-rise or large complex multi-storey buildings.

Description

technical field [0001] The invention relates to a steel-steel-concrete composite shear wall embedded with dense steel beams and outsourcing concrete composite shear walls between concrete-filled steel pipe columns and a manufacturing method thereof, which belongs to a novel steel-concrete composite shear wall that consumes earthquake-input structure energy and improves the seismic performance of the structure and its manufacturing method. The method belongs to the field of steel-concrete composite shear walls. Background technique [0002] At present, with the development of social production and the needs of human activities, there are more and more modern high-rise and super high-rise buildings, and the requirements for the seismic performance of shear walls are also getting higher and higher. Shear walls and core tubes composed of shear walls are the most critical vertical system for high-rise buildings to resist earthquakes, and they bear most of the seismic action of th...
