The stress analysis of the PCCP shell, which is a kind of concave polyhedral shells, is presented. Both the numerical method (FEM) and the experimental method are used in the analysis. Resultantly, the elastic behaviour and stress distributions of the PCCP shell subjected to either axial compression or hydrostatic pressure are made clear. The higher buckling pressures of PCCP shells in comparison with that of the circular cylinder are obtained experimentally. Besides, it was found that the particular stress distribution observed in PCCP shells in axial compression gave a basis for Miura's hypothesis to explain the collapsing mechanism of general cylindrical shells.
