abstract: In this paper, the phenomenon of interface crack propagation in concrete gravity dams under seismic
loading is addressed. This problem is particularly important from the engineering point of view. In fact,
besides Mixed-Mode crack growth in concrete, dam failure is often the result of crack propagation along
the rock-concrete interface at the dam foundation. To analyze such a problem, the generalized interface
constitutive law recently proposed by the first author is used to proper modelling the phenomenon of
crack closing and reopening at the interface. A damage variable is also introduced in the cohesive zone
formulation in order to predict crack propagation under repeated loadings. Numerical examples will
show the capabilities of the proposed approach applied to concrete gravity dams.
