The radial compression of the pipe results in the fitting being locked in place and prevents axial movement between the fitting and the pipe.

According to researches on SRC column with steel circle pipe, the calculation methods of the axial compression ratio and load bearing capability of normal section are put forward.
Based upon the elasticity theory, a mechanical model for the casing pipe was built and the relationship between residual stress and compression strength was developed by FEM.
