Problems solved by technology

However, the current application of composite steel plate walls in multi-tall building structures uses horizontal shear yield as the failure mechanism, and there is no super high-rise structural system that applies the vertical shear yield mechanism of composite walls

Embodiment 1

[0016] Embodiment 1: The super high-rise composite wall system of the present invention is made up of shear wall 1, composite steel plate wall 2, edge member 3 and steel frame beam 4, wherein, shear wall 1 adopts four-sided connection composite steel plate shear wall, composite steel plate Wall 2 adopts composite walls connected on both sides. Shear wall 1, which is the main anti-lateral force component of the structure, can use composite wall concrete slabs, which can be prefabricated or cast-in-situ. Concrete slabs. Controlling the thickness of the steel plates in the composite steel wall 2 and the thickness of the steel plates in the thick composite wall 1 makes the thin composite steel wall yield under large earthquakes while the steel plates in the composite wall 1 still maintain an elastic state. Edge member 3 can adopt steel column or SRC column. All edge members 3 are rigidly connected to the steel frame beams.

[0017] In order to verify the feasibility of the prese...

Abstract

The present invention belongs to the technical field of the structural engineering, and in particular relates to an ultra high-rise combined wall double structure system. The invention is composed of a beam column component, a stronger shear wall and weaker two-edge connecting assembling steel plate walls. In the system, a connecting-leg shear wall system is composed of a combined steel plate wall and a framework girder, and a thin combined steel plate wall which is only connected with the framework column is filled with a span which is provided with a steel coupling beam. The stronger combined steel plate wall is the combined steel plate wall which is connected at four edges and is restrained by the prefabricated or cast-in-place concrete plate at two sides. The concrete plate and the middle steel plate are connected with bolt. The thin combined steel plate wall is the thin combined steel plate which is only connected with framework columns at two sides and is restrained by the precast concrete plate at two sides. The steel coupling beam and the adjacent span adopt a rigid connection mode. The ultra high-rise combined wall system provided by the invention is suitable for the seismic zone and has a series of predominant characteristics of definite breakage mode in the function of the earthquake, high bearing capacity, large hardness at the resistant side, centralized damage, facilitating the reparation and the like. The combined wall system of the invention has excellent aseismic behavior, ductibility and hysteresis energy dissipation capability, and is a predominant shock resistant energy dissipating component.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a dual structure system of a super high-rise composite wall. Background technique [0002] As a new type of lateral force-resisting member, the composite steel plate wall combines the advantages of high ductility and good lateral stiffness of the steel plate shear wall. At the same time, the concrete slab is used to restrain the buckling of the steel plate and provide part of the lateral stiffness. Composite steel plate walls have been widely used in high-intensity seismic fortification countries such as Japan. In recent years, composite steel plate walls have also begun to be used in multi-story buildings in my country. Compared with ordinary concrete shear walls, composite steel plate walls have better ductility and energy dissipation capacity, overcome the shortcomings of brittle damage and difficult repair of concrete shear walls such as concrete cr...
