This paper uses the nonlinear prebuckling consistent theory to analyse the plastic bt1ckling problem of stiffened torispherical shell under uniform external pressure,The buckling equation and energy expressions of the shell are built. the calculation formula is presented. Numerical examples show that the method in this paper has better precision and calculating process is very simple.
