Problems solved by technology

[0004] At present, in the research field of cylinder structure, most of them are focused on the research of ordinary reinforced concrete cylinder, while the research results on the core cylinder with built-in steel plate are relatively few, 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

Embodiment 1

[0039] like figure 1 , 3, 4, the steel plate core tube is built in the bottom double-lapped steel concrete frame of the present invention, and the core tube is composed of a steel-concrete laminated frame column, a soft steel energy-dissipating steel plate 2 and surrounding shear wall panels. A shear wall steel plate 3 is arranged in the force wall panel, and a steel mesh composed of horizontally distributed steel bars 4 and longitudinally distributed steel bars 5 is arranged in the shear wall wall panels on both sides of the shear wall steel plate 3. Between the steel mesh The steel bars 6 are used to pull and connect each other; the steel-concrete laminated frame columns are set at both ends of the shear wall panels, that is, at the intersection of the shear wall panels, and are connected with the middle shear wall steel plate 3 as a whole; the steel-concrete laminated A mild steel energy-dissipating steel plate 2 is superimposed on the outside of the bottom of the section ...

Abstract

The invention discloses a section steel concrete frame inbuilt steel plate core cylinder with a doubly superimposed bottom, which is composed of a section steel concrete superimposed frame column, a power-wasting soft steel plate and a steel plate concrete shear wall. The section steel concrete frame inbuilt steel plate core cylinder with the doubly superimposed bottom is a doubly superimposed column of a superimposition of an externally stuck energy-wasting soft steel plate and a steel tube concrete column as well as a superimposition of the steel tube concrete column and a reinforced concrete column; and the section steel concrete frame inbuilt steel plate core cylinder with the doubly superimposed bottom 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 section steel concrete frame column and the steel plate shear wall. The section steel concrete frame inbuilt steel plate core cylinder with the doubly superimposed 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 normal reinforced concrete cylinders and has relatively steady earthquake resistant capability in a later stage. After 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 core tube with a steel plate embedded in a steel-concrete frame with double overlapping bottoms and a method thereof, which is a combined tube applied to high-rise buildings and belongs to the field of construction engineering. Background technique [0002] With the rapid development of my country's economic construction and the acceleration of urbanization, a large number of high-rise buildings have been built. In the selection of the structural system of high-rise buildings, factors such as improving the seismic energy dissipation capacity of the structure, reducing wind-induced swing, shortening the construction period, and reducing the cost are generally considered. The tube body composed of shear walls is the core part of high-rise building anti-seismic. Since high-rise buildings need to have greater lateral stiffness, the design of the lateral force-resistant structure is the key in the design, and the tube body is the ...
