Composite shear wall with concrete-filled steel tube frames and double steel plates with concealed bracings and construction method thereof

Abstract

A composite shear wall with concrete-filled steel tube frames and double steel plates with concealed bracings and a construction method thereof relate to the field of construction. According to the invention, the composite shear wall is formed by combining reinforced concrete frames, a double steel plate shear wall and steel plates with concealed bracings. The reinforced concrete frames are formed by pouring concrete into steel tubes; then, the double steel plates are placed, the double steel plates are welded to the reinforced concrete frames, and the steel plates are perforated and are connected through studs; oblique crossing concealed bracings are placed between the double steel plates, and the oblique angle of the concealed bracings is between 45 degrees and 60 degrees; tie bars are threaded through the interspace between the concealed bracings; a reinforcing mesh composed of transverse steel bars in horizontal arrangement and longitudinal steel bars in vertical arrangement is arranged between the concealed bracings and the steel plates; and concrete is poured between the double steel plates. The composite shear wall has the advantages that the bearing capability is enhanced, the bearing capacity and the rigidity attenuate slowly, the ductility and the energy dissipation of the shear wall are enhanced due to multi-defenses, and the earthquake resistant capability is more excellent. The composite shear wall also has the advantage of convenience in steel structure construction, and can be used in high-rise or large complex multi-storey buildings.

Description

Technical field [0001] The invention relates to a steel tube concrete frame double steel plate combined shear wall, in particular to a steel tube concrete frame double steel plate concealed support combined shear wall and a method of operation. Background technique [0002] With the development of social production and the needs of people's lives, there are more and more high-rise buildings. Large-scale and wide-area reinforced concrete high-rise buildings usually consist of beams, columns, floor slabs, shear walls and cylinders. The shear wall and the tube composed of the shear wall are the core part of the seismic resistance of high-rise buildings. The seismic performance of the shear wall structure plays a vital role in the safety and reliability of high-rise buildings. Especially in recent years, the number of large and complex high-rise buildings pursuing individualization has been increasing, and the requirements for the seismic performance of shear walls and cylinders com...

AI Technical Summary

Problems solved by technology

The existing reinforced concrete shear walls have poor ductility under earthquake action and are prone to brittle failure, which is very detrimental to the seismic performance of the overall structure
