Steel tube concrete frame inbuilt steel plate shear wall with soft steel sleeves at bottom and producing method of steel tube concrete frame inbuilt steel plate shear wall

Abstract

The invention relates to a steel tube concrete frame inbuilt steel plate shear wall with soft steel sleeves at the bottom and a producing method of the steel tube concrete frame inbuilt steel plate shear wall. The steel tube concrete frame inbuilt steel plate shear wall is composed of a steel tube concrete frame column, a soft steel sleeve and a shear wall steel plate. The steel tube concrete frame inbuilt steel plate shear wall with the soft steel sleeves at the bottom, disclosed by the invention, is a multi-combination body of a combination of reinforcing steel bars and concrete, a combination of the steel plates and concrete as well as a combination of the steel tube concrete frame column and the steel plate shear wall. The steel tube concrete frame inbuilt steel plate shear wall with the soft steel sleeves at the bottom, disclosed by the invention, has greater initial rigidity, higher bearing capability, slower attenuation of the bearing force and the rigidity as well as better integral quake-proof energy consumption performance than those of the traditional shear walls and has relatively steady earthquake resistant capability in a later stage as well as relatively light shear sliding damage at the bottom. After the soft steel sleeves are additionally arranged, the soft steel sleeve at the outer side is firstly yielded to consume energy of an earthquake input structure and can play resistance power and ductility functions even when the soft steel sleeve at the outer side is damaged, so that previous damage and destruction of the high-intensity steel plate can be prevented and delayed.

Description

technical field [0001] The invention relates to a steel plate shear wall with a steel pipe concrete frame with a soft steel casing at the bottom and a method thereof, which is a composite 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 de...

Problems solved by technology

[0004] At present, in the field of shear wall research, most of them focus on the research on ordinary reinforced concrete shear walls, and the research on steel plate concrete composite shear walls is relatively small, and the research on its seismic performance and structural measures is not deep enough. The anti-seismic energy dissipation capacity of its internal materials has not been deeply excavated
