The present study treats the nonlinear deformation characteristics of air-dome membrane structures under uniform internal pressure. An incremental load method based on a linear approximation or a mathematical programming method is applied to analyze the nonlinear deformation behaviors by minimizing the potential energy. As examples of numerical analyses, the deformation characteristics are shown for elliptic membrane structures with various kinds of fiber orientation angles, for a membrane structure with an initial deflection, and for cable-reinforced membrane structures.
