Abstract

Abstract

Based on the twin shear unified strength theory，it was analyzed the condition of load for the steel tube and the core-concrete under tri-axial compression，the formula of axial bearing capacity of steel reinforced concrete short column with double circular steel tubes was established whose influencing factors were analyzed． By the comparison between the results calculated by the formula and the test results，it shows good agreement． Meanwhile，applying the formula in this paper to an engineering example，higher accuracy can be found in this calculation than the results in relevant documents by the comparison between them and the finite element analysis results．
- unified strength theory,
- tri-axial compression,
- double circular steel tubes,
- ultimate bearing capacity
