Aluminum-steel combined steel-plate shearing wall

Abstract

The invention provides an aluminum-steel combined steel-plate shearing wall with greater force-resisting action, full material performance exertion and convenient mounting. The aluminum-steel combined steel-plate shearing wall comprises an upper connecting board, a core energy-consuming panel, a lower connecting board and edge components, wherein the upper connecting board is connected with the core energy-consuming panel which is connected with the lower connecting board; the upper connecting board and the lower connecting board are connected with a main structure of a building by the edge components; an aluminum panel with high plasticity, strong energy consumption and low yield point is adopted for the core energy-consuming panel which is additionally provided with horizontal and vertical reinforcing ribs and connected with the upper connecting board and the lower connecting board by high-strength bolts; and the upper connecting board and the lower connecting board are steel panels. The invention has stable and reliable working performance and favorable energy-consumption capability, can provide a certain accessional rigidity and accessional damping for the structure, effectively lighten the earthquake response of the structure and reduce the economic loss and casualties. The invention effectively improves the quake-proof performance of the structure, effectively decreases the manufacture price and the construction time and has the advantages of simple construction, low manufacture cost, strong suitability, and the like.

Description

(1) Technical field [0001] The invention relates to civil engineering technology, in particular to an aluminum-steel composite steel plate shear wall. (2) Background technology [0002] As a new type of high-rise lateral force-resistant structural system, steel plate shear wall has been widely used in western countries such as the United States, Japan and Canada. In recent years, it has also been applied in high-intensity seismic fortification areas in my country. Steel plate shear wall overcomes the shortcomings of reinforced concrete shear wall, such as excessive rigidity, low ductility, early crack generation and difficult repair after earthquake, and has the advantages of large initial stiffness, good plastic performance and stable hysteretic characteristics. It is a new type of seismic unit that can absorb seismic energy. The existing various forms of steel plate shear walls mainly have the following deficiencies: (1) Thick steel plate shear walls or stiffened rib ste...

AI Technical Summary

Problems solved by technology

There are mainly the following deficiencies in the existing various forms of steel plate shear walls: (1) thick steel plate shear walls or stiffened steel plate shear walls have good energy dissipation energy, large rigidity and shear bearing capacity, but Its biggest disadvantage is the waste of materials and high cost; (2) thin steel plate shear wall, the hysteretic curve under repeated loads has a relatively severe pinching phenomenon, which is not conducive to the consumption of energy input by the steel plate; (3) combined steel plate The shear wall cannot be opened on the steel plate wall, and the steel plate shear wall cannot be used as a lateral force-resisting member in the place where the opening needs to be opened.
