Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] In an office building in a certain city in Hebei Province, the core structure is planned to adopt the composite shear wall filled with concrete inside the outer-wrapped multi-cavity profiled steel plate of the present invention, the wall thickness is 2m, and the wall length is 11m. The external multi-cavity profiled steel plate is filled with a concrete composite shear wall 1, which is filled with concrete 3 in two oppositely arranged profiled steel plates 4, and the composite shear wall 1 is welded with multiple pieces in the middle of the composite shear wall 1. Thin steel plates 2 of the same length as the wall, and steel columns 5 are respectively welded to the two ends of the profiled steel plates 4, so that the combined shear wall 1 forms a peripheral closed structure; the profiled steel plates 4 are corrugated, and the thin steel p...

Abstract
The invention relates to a composite shear wall with multi-cavity profiled steel plate filled with concrete, which is filled with concrete in two oppositely arranged profiled steel plates, and the composite shear wall is welded with multiple pieces in the middle of the composite shear wall. Thin steel plates of the same length as the wall, and steel columns are welded at both ends of the profiled steel plates, so that the combined shear wall forms a closed structure around; the profiled steel plates are corrugated, and the thin steel plates are welded at equal intervals. In the outsourcing multi-cavity profiled steel plate filled with concrete composite shear wall of the present invention, a thin steel plate is welded in the middle of two profiled steel plates to serve as stiffeners and connectors, and the closed profiled steel plate has a strong restraint effect on the concrete , at the same time, the presence of stiffeners improves the stable bearing capacity of the profiled steel plate. While ensuring the high compressive bearing capacity of the composite wall, it improves its deformation capacity, simplifies the structure of the shear connectors, and improves the utilization of materials. Rate.
Description
technical field [0001] The invention relates to a novel composite member, which belongs to the technical field of structural engineering, and in particular to a composite shear wall with multi-cavity profiled steel plates filled with concrete, which is suitable for multi-high-rise building structures. Background technique [0002] In the structural design of high-rise buildings, the selection of lateral force-resisting system becomes a crucial factor. Shear walls are efficient structural elements that resist horizontal forces in buildings. From the earliest masonry and masonry shear walls to reinforced concrete shear walls and steel plate shear walls, it is a process of structure development towards high strength, light weight, high ductility, and efficient construction. , The process of complex structural and functional requirements. Reinforced concrete shear walls are favored by the majority of designers for their advantages of good integrity, high rigidity, small latera...
