A deflection analysis of the wrinkled membranes subjected to a uniformly distributed load was performed by a nonlinear finite element analysis based on the tension field theory and shell theory, and an effectiveness of the deflection shape estimated from the analysis with the tension field theory was investigated from the view points of the shell theory. Through the comparison on the simulation results given by both theories, it was presented that the membrane surface features calculated from the analysis with tension field theory does not always represent the intermediate surface features of the wrinkled membranes given by the analysis with the shell theory.
