Summary Inflatable dams are used for various purposes in a number of countries. They are cylindrical membrane structures which are attached to a rigid foundation along two of their generators and are inflated with water, air, or a combination of water and air. Some studies of their cross-sectional static profiles have been carried out in the past, both for cases when the dam impounds water and when overflow occurs. Experiments on scale models also have been reported. Vibrations have been observed on actual dams and on the physical models, but a theoretical analysis of the dynamic behavior of inflatable dams has not been published previously. In this paper, two-dimensional linear vibrations are considered. The dam is inflated with water and is used to impound water. Its material is assumed to be inextensible. Vibration modes and frequencies are obtained with the use of the finite difference and boundary element methods. The effects of the membrane density, internal head, and upstream head on the frequencies are determined.
