Study on the Buckling Analysis of Stiffened Spherical Shallow Shell for Gasholder Roof
Subjected to external pressure, buckling analysis is key problem in the roof shell design of large scale cylinder gasholder. Two simplified buckling analysis methods, the continuous orthotropic plate method and the split-rigidity method, are introduced to check the general instability of stiffened spherical shallow shell. Considering the plate and the stiffeners in two directions with the same contribution to the bending stiffness, the equivalent bending thickness formula is put forward. The finite element model for a 100,000 m³cylinder gasholder roof is setup. The buckling critical loads obtained prove that the split-rigidity analysis method and formulae are applicable. The results can be referred in design of stiffened spherical shallow shell.
