Description

Office Space Concrete Steel Column Design Structure

technical field

Background technique

Concrete-filled steel pipe columns refer to members formed by filling concrete in steel pipes. According to the different cross-sectional forms, it can be divided into round concrete-filled steel tube columns, square and rectangular steel tube concrete columns and polygonal steel tube concrete columns. Among them, rectangular steel tube concrete columns and circular steel tube concrete columns are widely used. The concrete-filled steel tube column utilizes the interaction between the steel tube and the concrete during the stress process, that is, the restraint effect of the steel tube on the core concrete, so that the concrete is in a three-dimensional compression state, the strength of the concrete is improved, the plasticity and toughness are improved, and at the same time It overcomes the shortcoming that the steel pipe is prone to local buckling. In addition, during the construction of steel pipe concrete, the steel pipe can also be used as a formwork for pouring core concrete. Compared with reinforced concrete, it can save formwork costs and speed up construction. The combination of steel pipe and concrete into steel pipe concrete can not only make up for the respective shortcomings of the two materials, but also give full play to the advantages of both. However, the defects of the existing construction structure and methods are: a large amount of manpower and material resources are required, the fireproof performance is insufficient, the columns are deformed after bearing the load, and the surface layer is damaged by cracks.
