Abstract

With consideration of the intermediate principal stress,the calculation formula of bearing capacity of RPC filled steel tube columns under axial compression was deduced based on the twin shear unified strength theory．Combining with the bond-slip theory,new ultimate bearing capacity formula was derived with the highest regard for bond stress．Compared with the theoretical result and the experimental data,good agreement could be found．The results show that unified strength theory and the bond-slip theory are versatile in theoretical analysis of the column．The analysis results can provide a theoretical basis for the optimum design of RPC filled steel tube and the solution has an important practical value for engineering application．
