Abstract
The utility model discloses a shearing wall with mild steel sleeves at bottoms and hidden steel plates in a concrete-filled steel tube frame. The shearing wall consists of concrete-filled steel tube frame posts, mild steel sleeves and steel plate shearing walls. The shearing wall disclosed by the utility model is multiple combinations including a combination of reinforcing steel bars and concrete, a combination of steel plates and concrete, and a combination of concrete-filled steel tube frame posts and steel plate shearing walls. Compared with the traditional shearing wall, the shearing wall with mild steel sleeves at bottoms and hidden steel plates in the concrete-filled steel tube frame has the advantages of higher initial rigidness, higher bearing capability, slow reduction of bearing force and rigidness, good earthquake-proofness and energy consumption of the whole structure; the final earthquake-proof performance is relatively stable; when the bottoms are shorn, the sliding failure is slighter; after the mild steel sleeves are additionally arranged, the outside mild steel sleeves are yielded at first to consume energy input into a structure by an earthquake and can play resistance and ductility roles till the mild steel sleeves are damaged, so that the early damage and destroy of high-strength steel plates are prevented and delayed.
Description
Technical field
The utility model relates to the built-in steel plate shear force wall of a kind of bottom band mild steel sleeve pipe steel pipe concrete frame, is a kind of compound shear wall that is applied to highrise building, belongs to building engineering field.
Background technology
Highrise building is the product of economic development in modern times and scientific progress.Shear wall and be the core of highrise building antidetonation by the cylindrical shell that shear wall is formed; Because highrise building needs bigger lateral rigidity; Therefore in the design; The design of lateral resisting structure is crucial, and shear wall is as one of main lateral resistant member, and its service behaviour under geological process has crucial effects to the security performance of total.The highrise building bottom member will bear bigger horizontal loading and vertical load usually, so the development of modern high-rise building is to the demands for higher performance of shear wall member.
Because the large complicated highrise building of pursuing individualityization is increasing, we are also increasingly high to the requirement of Seismic Property of Shear Wall Structures.Existing ordinary reinforced concrete shear wall ductility under geological process is relatively poor, easy brittle destruction af-ter, and this anti-seismic performance to total is very unfavorable.The steel-concrete compound shear wall combines reinforced concrete structure and steel work, can remedy shortcoming separately, brings into play their advantage better, makes structure have bigger bearing capacity and rigidity, has better ductility and energy dissipation capacity.Because highrise building generally all needs bigger anti-side rigidity, so the design of shear wall must consider the design of lateral resisting, also should satisfy the requirement of providing fortification against earthquakes simultaneously.The steel plate concrete compound shear wall is a kind of cost-effective novel anti side force system, has both satisfied the requirement of anti-side rigidity, has satisfied the requirement of ductile performance again.
At present; In the shear wall research field; Focus mostly in research to the ordinary reinforced concrete shear wall; Research to the steel plate concrete compound shear wall is relatively also fewer, and is deep not enough to the research of its anti-seismic performance and construction measure, and its internal material energy dissipation ability is not carried out deep excavation.
