Membrane structures seem to be increasingly constructed for their own characters. In these structures, we research Air-Beam, which is a long and slender cylindrical shell membrane, is investigated as a beam after internally pressured, and wrinkling phenomenon, a kind of collapse state, reduce their stiffness and give influence to mechanical behavior. Therefor in this research, a numerical analysis for these structures based on FEM is proposed, which formulated the analysis of wrinkling behavior employing beam element, effective area contributed for stiffness that rely on stress state after wrinkling has taken place are defined.
