Metodologias para o cálculo sísmico não-linear de barragens de betão

In this monograph the basic methodologies for the non-linear seismic analysis of concrete dams are presented. The Finite Element Method is used to discretize the dam-foundation-reservoir ensemble, whereas the dynamic equations will be solved in the time domain according to implicit integration schem...
