Manufacturing method of bottom double composite section steel shear wall with reinforced concrete frame and inside-hidden steel plate

Abstract

The invention relates to a bottom double composite section steel shear wall with a reinforced concrete frame and an inside-hidden steel plate as well as a manufacturing method. The shear wall comprises a steel reinforced concrete composite frame column, a mild steel energy-consuming steel plate and a shear wall steel plate, which is a double composite column comprising the composite of the externally-adhered mild steel energy-consuming steel plate and a concrete filled steel tube column and the composite of the concrete filled steel tube and a reinforced concrete column and is a multiple combination body comprising the combination of a reinforcing bar and concrete, the combination of a steel plate and the concrete and the combination of a steel reinforced concrete frame column and a steel plate shear wall. Compared with a conventional shear wall, the shear wall provided by the invention has the advantages of high initial stiffness, high bearing capacity, slow bearing capacity and stiffness attenuation, good whole anti-seismic energy-consuming performance and relatively stable later-stage anti-seismic performance; the bottom shear-slip damage is little; and after a mild steel casing pipe is added, the outer mild steel casing pipe is firstly surrendered so as to consume the energy in the structure input by earthquake and can give play to the effects of resistance and ductility till being destroyed, therefore, the premature damage and destroy of the high-strength steel plate can be prevented and delayed.

Description

technical field [0001] The invention relates to a steel plate shear wall with a built-in steel-concrete frame with double overlapping bottoms and a method thereof, which is a combined shear wall applied to high-rise buildings and belongs to the field of construction engineering. Background technique [0002] High-rise buildings are the product of modern economic development and scientific progress. The shear wall and the cylinder composed of the shear wall are the core parts of high-rise building anti-seismic. Since the high-rise building needs to have a large lateral stiffness, the design of the lateral force-resistant structure is the key in the design, and the shear wall is the main It is one of the anti-lateral force members, and its working performance under the action of earthquake plays a vital role in the safety performance of the whole structure. The bottom components of high-rise buildings are usually subjected to large horizontal and vertical loads, so the develo...
