Concrete composite shear wall

Abstract

The invention discloses a concrete composite shear wall, which includes a wall body and side columns, wherein the wall body is fixedly connected with the side columns. The wall body comprises a binding bar array and double-layer metal plates; interlayer is formed between the double-layer metal plates; concrete wallboards are arranged in the interlayer, the binding bar array penetrates the double-layer metal plates, and the concrete wallboards are tightly fixed inside the double-layer metal plates through the binding bar array; the binding bar array is distributed in block form or in quincuncial form; the side columns are steel pipe concrete side columns formed by steel pipes and concrete columns in the steel pipes; the steel pipes of the steel pipe concrete side columns are welded and fixed with the double-layer metal plates. The concrete composite shear wall has high bearing capacity, excellent seismic resistance, high ductility, reasonable stress and the like, thereby being suitable for high level and super high level core tube shear walls.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a concrete composite shear wall. Background technique [0002] In recent years, with the rapid development of social economy and the continuous improvement of construction technology, more and more high-rise and super high-rise large complex buildings have sprung up. At present, the hybrid structure system often used in super high-rise buildings is a new structure system with good wind resistance, earthquake resistance and good economy. However, since the shear walls of the core tube of the hybrid structure often bear more than 80% of the seismic shear force, and some even bear the entire shear force, the frame only bears the vertical force, and the shear-span ratio of the shear wall at the bottom of the structure is generally small. At the same time, the axial compression ratio is very large, so the seismic performance of the entire structural system depends to a la...

In addition, due to the requirements of the code for the calculation of the shear-weight ratio and the floor shear force borne by the outer frame columns, when the thickness of the shear wall increases, the section of the outer frame columns must also increase accordingly, resulting in increased costs and overall structural control. difficult situation
