A Concrete Arch Dam under Seismic Loading Conditions
A new regulation for the safety assessment of dams has just been developed in Italy and its approval process is still in progress. As a matter of fact the behaviour of dams under seismic loading conditions is deemed of actual interest due to the recent seismic events occurred. In earthquake analysis, some of the most challenging aspects dam engineers have to deal with are: the capability to take duly into account the dam-reservoir and foundation rock-reservoir interactions; a careful evaluation of the maximum displacements/stresses of the concrete structures; a proper choice of constitutive models. This paper shows how COMSOL Multiphysics® can afford the safety assessment of a large concrete arch dam under dynamic excitation, taking into account the dam-reservoir and foundation rock-reservoir interactions as well.
