This book evaluates the seismic performance of concrete gravity
dams, considering the effects of strong motion duration,
mainshock-aftershock seismic sequence, and near-fault ground
motion. It employs both the extended finite element method (XFEM)
and concrete damaged plasticity (CDP) models to characterize the
mechanical behavior of concrete gravity dams under strong ground
motions, including the dam-reservoir-foundation interaction. In
addition, it discusses the effects of the initial crack, earthquake
direction, and cross-stream seismic excitation on the nonlinear
dynamic response to strong ground motions, and on the
damage-cracking risk of concrete gravity dams. This book provides a
theoretical basis for the seismic performance evaluation of high
dams, and can also be used as a reference resource for researchers
and graduate students engaged in the seismic design of high dams.
