NONLINEAR BUCKLING OF CYLINDRICAL DOUBLE-DECK RETICULATED SHALLOW SHELLS

Based on the nonlinear bending theory of double-deck reticulated shallow shells, the nonlinear buckling problem of cylindrical double-deck reticulated shallow shells under uniform transverse pressure is studied. An analytic solution for the shell with simply supported edges is obtained by use of Galerkin抯 method. The results of numerical calculations are presented in diagrams, showing the influence of geometrical parameters on the buckling behavior of cylindrical double-deck reticulated shallow shells.
