Abstract

The invention relates to a steel tube concrete column-double-layer steel plate combined shear wall belonging to the technical field of constructional engineering and combination structures. The steel tube concrete column-double-layer steel plate combined shear wall comprises two steel tubes, two steel plates, distributed reinforcing steel bars, connecting keys, male pins and concrete, wherein the connecting keys are vertically and alternately arranged at the opposite sides of the two steel tubes; both ends of each of transversally distributed reinforcing steel bars in the distributed reinforcing steel bars are respectively connected with the connecting keys in corresponding positions on the two steel tubes; the male pins are welded on the opposite sides of the two steel plates; two lateral ends of the two steel plates are connected with the steel tubes; and concrete is cast in the two steel tubes and in a planar closed space encircled by the two steel plates and the two steel tubes. The shear wall of the invention can restrict the concrete from deforming, improve the bearing capacity and the tensility of the shear wall and enhance the whole quake-proof performance of the structure. Moreover, the shear wall has favorable stress performance and improved quake-proof performance, is favorable to engineering of building space arrangement, decreasing self weight and reducing template engineering and is suitable for being used as a shear wall in a high-rise or ultra-high-rise building.

Description

technical field [0001] The invention relates to a steel pipe concrete column-double-layer steel plate composite shear wall applicable to high-rise and super high-rise buildings, belonging to the technical field of construction engineering and composite structures. Background technique [0002] Shear walls, or cylinders composed of shear walls, are the main lateral force-resisting components of high-rise buildings. With the increase of building height and the improvement of building function requirements, the requirements for all aspects of shear walls are getting higher and higher. Traditional concrete walls have poor deformation capacity and low ductility, which directly affect the seismic performance of high-rise buildings; excessive vertical loads require a large shear wall thickness to meet the "Seismic Design Code" for shear wall axis The pressure ratio limit; too thick walls increase the weight of the structure, which is not conducive to earthquake resistance, and at ...
