Protecting some regions against flooding requires the construction of some dams, which are complex constructions, capable of withstanding various demands mainly due to the increase of the water level above certain limits. Dams with a gate are often used for this purpose and the paper aims to study the vibrations that occur at such a gate. The analysis is done on an innovative project of a dam with an oscillating central pivot. For the studied system, the frequencies and modes of vibration are determined. A study of forced vibrations is also carried out, determining the response of some sensitive points of the dam to a periodic excitation. The Finite Element Method is used to obtain the results.
