An analytical method has been developed to calculate the deformations and stresses of the wall plates of dry gas holders subject to gas pressure. The deformations of the wall plates are decomposed into out-plane bending and in-plane deformation which are analyzed with the theories for orthotropic plates and flat plates under plane stress, respectively. The analytical formulas to calculate the deformations and stresses in the wall plates are obtained. They give very agreeable results to those of finite-element analysis. Due to the simplicity of the proposed method, it is especially suitable for the analysis and design of the wall plates of dry gas holders under gas pressure.
