The present paper specifies fundamental vibration characteristics of the suspension membrane structure. Quadrilateral and approximate hyperbolic parabolic shaped membrane models are experimented to examine free vibration characteristics under several initial applied tensile forces or initial applied amplitudes. From these experimental results, it is obtained that the vibration characteristics strongly depends on the initial applied amplitude, and added mass of the air is necessary to be considered in analyzing on the experimental data. Displacement response wave forms obtained from the experiments are also examined by nonlinear response analysis. From the analytical result, it is possible to clarify the vibration characteristics qualitatively. Consequently, by the analysis it is examined influence of initial state of the membrane shape on its vibration characteristics; therefore, it is predicted how state of shape is necessary to check its vibration characteristics in the design process.
