Dams are built to serve for a long time of reliable and safe operation. Many dams are under operation since a long time period. During the operation of those old dams not only essential part of the design philosophy but also construction methods have changed to cope with the state of the art knowledge. During the last years strong earthquakes forced loss of life and devastation of property and infrastructure. However, no dam failure occurred with devastating impact and only few of them suffered or were destroyed due to earthquake shaking. Nevertheless it is of great importance to pay attention to earthquake loading of dams to minimize possible risks. Especially when building dams in foreign countries and earthquake loading is more severe it is necessary to adapt design procedure for local circumstances. Within this contribution the long term behaviour of concrete dams together with the process of ageing are described with special regard to regulations devoted to earthquake adequate design. As example for the application of design regulations to safety assessment as part of the long term behaviour of dams a gravity dam and two arch dams are exercised.
