Abstract

Abstract

In this article the initial postbuckling behavior of ring stiffened cylindrical shells under hydrostatic pressure is analyzed by Koiter's theory.The nonlinear bending equations consistent with boundary conditions have been used in prebuckling slate.The eigenvalue problem is solved by Galerkin's method.The obtained buckling loads are compared with the results which are based on classical stability theory.As calculating examples, three typical outside-stiffened cylinders with different ring stiffener parameters are chosen.The results show that the strength of stiffener not only influences buckling load obviously, but also changes the imperfection-sensitivity of cylindrical shells.
