Two-side-connection combined steel plate shearing force wall

Abstract

The invention belongs to the technical field of the structural engineering, and particularly relates to a shear wall with the two sides connected with a combined steel plate; a bolt connects a steel plate filled internally and a concrete slab hung outside to form a combined steel plate wall and a wall body is only connected with a frame beam without being connected with a frame column, thus forming the shear wall with the two sides connected with the combined steel plate; out-of-plane support is carried out to the connected wall body at the two sides by a support frame, thus guaranteeing the stability of the outside of the plane of the wall body and leading the wall body to consume power effectively under a major earthquake; the product can replace the shear wall with the four sides connected with the steel plate, has wider application than the shear wall with the four sides connected with the steel plate and can be widely used for multistoried and high-rise steel structure and steel-concrete combined structure, thus being especially applicable for multistoried and high-rise steel structure in which a door opening is arranged and the layouts of buildings are various.

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 connected on both sides. Background technique [0002] At present, pure steel plate shear walls with four-sided connections are generally used in similar fields. Under a relatively small load on the pure steel plate wall specimen, the thin steel plate buckles locally, resulting in a large in-plane deformation, so the hysteresis curve shows obvious pinching phenomenon, and the energy dissipation capacity of the steel plate cannot be fully utilized . [0003] The combined steel plate wall is covered with concrete slabs on both sides of the steel plate, and the two materials are connected by bolts, and the concrete wall plate is used to prevent the out-of-plane buckling of the steel plate. Can greatly reduce costs. [0004] The traditional four-sided steel plate wall needs to be connected with the frame beam and column...

AI Technical Summary

Problems solved by technology

[0004] The traditional four-sided steel plate wall needs to be connected with the frame beam and column by the inner filling steel plate, which will inevitably lead to two adverse effects. First, the additional bolt holes and bolt connections increase the construction volume and cost; second, the inner filling steel plate The full play of strength requires beams and columns to provide reliable anchorage, which will bring adverse effects to the column, and the column flange will buckle obviously. As the vertical load-bearing member of the building, if the column is damaged, will likely lead to the collapse of the entire structure

In addition, there is another defect of the four-sided steel plate wall that no holes can be opened on the steel plate wall. In this way, the steel plate wall cannot be used as a lateral force-resistant member in the place where openings need to be opened in the building, thus greatly reducing the steel plate wall. Application range as a new type of component

The composite steel plate shear wall with four-sided connection utilizes the restraint effect of the concrete slab on the inner filling steel plate to prevent out-of-plane buckling of the steel plate. significantly

[0005] At present, there is no relevant patented technology to propose composite steel plate walls connected on both sides. With the development of high-rise steel structures in my country, especially the development of high-rise steel structure residences, the development of new lateral force-resistant structural components is also imperative.
