Background technology
Steel core concrete column is a kind of new and effective combined member developed in recent years, and it is by steel pipe and steel pipe
Coagulation local soil type into.By the performance of compound action, concrete filled steel tube can give full play to the material of both steel and concrete
Performance.Due to the effect of pipe inner concrete, the stability of steel pipe wallboard is greatly improved, it is to avoid or delayed steel plate wallboard mistake
It is early that local buckling occurs.Further, since effect of contraction of the steel pipe to concrete, the compression strength and deformability of concrete are obtained
Significantly improve.Steel pipe is also used as the template of concreting, so as to greatly shorten the duration.Due to above-mentioned advantage, steel pipe is mixed
Solidifying earth pillar has obtained increasingly being widely applied in Practical Project.For steel core concrete column, in other conditions identical feelings
Under condition, steel yield strength is higher, and the effect of contraction of steel pipe is stronger, and the bearing capacity of post is higher.Therefore in bearing capacity identical feelings
Under condition, the sectional dimension of steel core concrete column, saving steel can be reduced using high strength steel pipe.But in high strength steel pipe concrete
While post reduces sectional dimension, its rigidity of structure also accordingly reduces, and deformation more difficult satisfaction of the structure under small shake effect
Ask.And compared to common steel tube, high strength steel pipe is more easy to local buckling before yield strength is reached, strong so as to constrain steel pipe
The performance of degree.
The content of the invention

Zygostyle structure.
Technical scheme is as follows：
A kind of concrete filled steel tube composite column structure with ribbing surrendered stage by stage, including a steel pipe, have poured coagulation in steel pipe
Soil, and the inward-facing vertical projection of inwall of the steel pipe is spacedly distributed and some longitudinal floors isometric with steel pipe, each longitudinal direction
The yield strength of floor is below the yield strength of steel pipe, and under geological process, above-mentioned some longitudinal floors can bend prior to steel pipe
Take to consume the energy of Seismic input, prevent or delay above-mentioned steel pipe premature harm and destruction；
Spacing between the adjacent longitudinal ribs plate of above-mentioned some longitudinal floors is the 20~35% of steel pipe width, each longitudinal direction
The thickness of floor is the 30~50% of the wall thickness of steel pipe, and the gross area of some longitudinal floors is the gross area of the side wall of steel pipe
30~50%.
In a preferred embodiment of the invention, the spacing between the adjacent longitudinal ribs plate of some longitudinal floors
It is the 1/4~1/3 of steel pipe width.
In a preferred embodiment of the invention, the thickness of each longitudinal floor be the wall thickness of steel pipe 1/3~
1/2。
In a preferred embodiment of the invention, the gross area of some longitudinal floors is the total of the side wall of steel pipe
The 1/3~1/2 of area.
It is further preferred that the cross section of the steel pipe is rectangle.
It is further preferred that the cross section of the steel pipe is circle.
Beneficial effects of the present invention：The increasing in steel pipe of the concrete filled steel tube coupled column with ribbing surrendered stage by stage of the invention
If longitudinal floor of low-yield.Low-yield longitudinal direction floor enhances the local stability of steel pipe, meanwhile, low-yield is indulged
Can be surrendered prior to high strength steel pipe to floor, consume the energy of Seismic input structure, prevent mistake of the high strength steel pipe under big shake effect
It is early to damage and destroy, the deficiency of common concrete filled steel tubular column is compensate for, had broad application prospects in skyscraper.
