摘要：
Based on the twin shear unified strength theory, considering the impact of the intermediate principal stress sigma(2) and the different effects of material' tensile and compressive properties, this paper deduced the axial compressive bearing capacity formula of core column with high strength concrete filled steel tube. Compared the results of the paper with the test, both coincide in good condition. The results show the validity of the formula. The theoretical formula provides a theoretical basis in the project application and design on the core column with high strength concrete filled steel tube.
