Combined steel plate shearing force wall with large aspect ratio

Abstract

The invention belongs to the technical field of structural engineering, in particular to a large height-width ratio combined steel plate shear wall; the large height-width ratio combined steel plate shear wall comprises a frame beam, concrete slabs and steel plates, and is characterized in that: the middle parts of the steel plates are weakened, which causes the cross sections of the middle parts to be smaller than those of connecting parts at two ends; the height to width ratio is more than 1; in order to prevent excessively centralized stress, transition zones are respectively arranged at variation parts of the cross sections of the middle parts and the two ends of the steel plates; the steel plates are connected with the concrete slabs through bolts. By adopting the large height-width ratio steel plate shear wall, the need for arranging walls among the windows in the buildings is met, and components are mainly bent rather than sheared in structure. The steel plates are connected with the concrete slabs through bolts, the steel plates with large height-width ratio are limited by the concrete slabs, and the cross sections of the middle parts of the steel plates with large height-width ratio are weakened, thereby avoiding local failures of the supports occurs before the whole steel plates are bent, and ensuring an excellent ductility. The large height-width ratio steel plate shear walls can be widely used in the residential systems with various architectural layouts and multi-story steel structures.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a composite steel plate shear wall with a large aspect ratio. Background technique [0002] At present, the steel plate shear wall with small aspect ratio is generally used, that is, the ratio of the height to the span of the steel plate shear wall is less than 1. However, when used in actual buildings, due to the needs of indoor traffic or the layout of building doors and windows, it is sometimes not allowed to arrange large-width steel plate shear walls, and only narrower positions can be equipped with steel plate walls. Therefore, a new type of steel plate shear wall is proposed, the height is greater than the width, and the out-of-plane deformation is restrained by precast concrete plates on both sides of the steel plate, which is called a high aspect ratio composite steel plate shear wall. [0003] At present, there is no relevant patented technol...

Problems solved by technology

[0003] At present, there is no relevant patented technology to propose high-height-width-ratio steel plate walls. With the development of high-rise steel structure residential buildings in China, it is imperative to develop new lateral force-resistant structural members suitable for steel structure residential systems.
