Bifuntional combined steel plate shear wall

Abstract

The invention relates to a bifuntional combined steel plate shear wall. A specially designed T-shaped fish-belly plate shear resisting system enhances the shear resisting stiffness in small earthquakes or in middle earthquakes, realizes stable transmission force, and augments the stiffness of the simply used steel shear wall; in large earthquakes, the shear resisting system quits operation, and partially provides the shear resisting stiffness; a plug-in concrete slab does not involve to share the horizontal effect, so as to lower the whole resist lateral stiffness; simultaneously the shear resisting system ensures the restraining effect of the concrete slab to the outer side of the steel plate, improves the energy consuming ability of the structure, augments the additional damping ratio of the structure, and decreases the damage effect of the structure in the earthquakes, thus achieving the effect of a fuse wire and a energy dissipater in large earthquakes. The bifuntional combined steel shear wall provided by the invention is a novel combined steel plate shear wall applied in high-rise building steel structures or other structures, has simple construction, convenient replacement, good economy, better vibration resistance and the like, and is a superior and practical side force resisting structural member.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a double-function combined steel plate shear wall. Background technique [0002] Due to its unique structure and utility, the composite steel plate shear wall has become a component form with better comprehensive performance. The steel plate shear wall mainly utilizes the energy consumption of the steel plate. On the one hand, the concrete slabs on both sides provide lateral restraint for the inner filling steel plate to prevent out-of-plane buckling of the steel plate; etc., the two are connected by high-strength bolts to form a wall component. In other words, the advantages of high bearing capacity, good ductility, and quick construction of steel plates and high rigidity and good fire resistance of concrete slabs are used to complement each other. [0003] In the traditional combined steel plate shear wall, the built-in steel plate directly bear...

AI Technical Summary

Problems solved by technology

Under the action of small earthquakes or wind loads, the lateral stiffness of the structure is entirely provided by steel plates, which is poor in economy and limited in bearing capacity

There are two structural forms between the concrete slab and the edge member: one is the close contact between the two. In this way, the concrete slab participates in resisting the horizontal force, but it will be damaged when the deformation is large, and the protective effect on the steel plate will be lost; the other is The first form is to reserve a gap between the two, so that during the entire deformation process, the concrete slab does not participate in resisting the horizontal force, but only undertakes the protection of the steel plate. The disadvantage is that under the action of small earthquakes and wind, the lateral stiffness is completely provided by the steel plate , less economical
