Free vibrations of inflatable dams
This work deals with the linear two-dimensional free vibrations of an inflated cylindrical membrane. An air-inflated membrane is considered first. Vibration frequencies and modes are determined for various cases. The lowest mode shape is anti-symmetric. In the rest of the work, the membrane is …

Nonlinear vibration analysis of inflatable dams
In recent years the use of inflatable dams has become more widespread throughout the world. Various people have done studies on the shape and membrane tension of these structures; however, only a few authors have considered dynamic behavior. Due to the nature of the applications and the material …

Vibration Analysis of Single - Anchor Inflatable Dams
Inflatable dams are flexible, cylindrical structures anchored to a foundation. They are used for a variety of purposes, e.g. diverting water for irrigation or groundwater recharging, impounding water for recreational purposes, and raising the height of existing dams or spillways. The vibration …

Experimental investigation on the dynamics of inflatable dams
… of pressurized cylindrical membranes used as dams are considered here. Single-anchored air-inflated membranes are predominantly studied. Load combinations are considered without any water, with impounding water, and with water overflow. The two major experimental variables are the dam's …

Analysis of the vibrations of inflatable dams under overflow conditions
… analysis is applied to the vibrations of inflatable dams under overflow conditions. The static analysis yields the equilibrium state for both the free surface profile and the shape of the dam. The dynamic analysis investigates the small vibrations of the inflatable dam about the …

Effect of membrane weight on vibrations of air-inflated dams
Inflatable dams are flexible membrane structures, pressurized with either air, water, or both, which have been used in recent years as a means of temporarily impounding water. A number of procedures have been developed to investigate the static behavior of the dams, but the dynamic behavior has …
