This document deals with the whole process compression model test on 12 short columns of separation concrete-filled steel tubes (CFST) which are subjected to eccentric compression on the non-separation side. The experimental parameters include the separation ratio and the eccentricity ratio. The results show that the separation ratio and the eccentricity ratio will influence CFST components’ mechanical properties which contain the relationship of load-strain amd load-deformation, that especially embodied in the nonlinear stage. When compressed on non-separation side, the confinement of steel tubes to core concrete will be continuously weakened and the ultimate load capacity of the components will be decreased obviously with both the separation ratio and the eccentricity ratio increasing gradually. But it less serious which compare with that compressed on separation side.
