Based on the experimental research theory of concrete-filled steel tube based on experiments, the internal strength is calculated by using the integrated strength value represented by the coefficient of the concrete-filled steel tube, which is a semi-theory and semi-empirical method. In this paper, the cross-section strength of the radial load is obtained by calculating the hoop tightness of the steel pipe, and the separate separation of the bearing capacity of the steel pipe hoop is achieved. The internal force of the concrete-filled steel tubular short column can be divided into the strength of different materials to calculate, and the internal force superposition. This method is intuitive and simple. It selects the strength calculations at different stages of the material. The calculated results are in agreement with the theoretical values. It is a new exploration of the calculation method for the strength of concrete filled steel tubular short columns.
