Book Description
Earthquake Engineering for Dams and Reservoirs is an invaluable source for any engineer, or designer, tasked with building, retrofitting or maintaining dams in all seismically active regions to make decisions on the type of dam structure required for new projects and understand the issues that face existing dams and how to mitigate them.

Book Description
Most existing arch dams have been designed for seismic loading by static methods involving the use of seismic coefficients. Although there are no known examples of arch dams which have been seriously damaged by earthquakes, the need for more realistic seismic analyses is now well recognized, not only for new dams but especially in the context of the safety evaluation of existing dams. Fortunately, with the finite element method, engineers have a powerful tool for modeling the complex geometry and the nonlinear material behavior of a dam. However, there is still a major complication in the analysis procedure, namely the interaction of the dam with the reservoir and with the foundation during an earthquake. Interaction is a wave propagation problem involving transmitting boundaries. The State of the Art in engineering practice is to neglect wave propagation by modeling the water as incompressible and the foundation as massless. More advanced analysis methods using compressible water and foundation with mass have been available for some time. However, these methods are restricted to linear models, because they work in the frequency domain. On the other hand, there are also advanced nonlinear models for dams, but they can only be used in the time domain, usually with simple transmitting boundaries. In this report, which is based on an a doctoral thesis, rigorous transmitting boundaries in the time domain are developed which permit combining compressible water with n- linear dam behavior. The new numerical model is based on a systems-theory approach.

Book Description
Discusses, in a unified manner, the theoretical and practical aspects of the seismic behavior of all types of concrete and embankment dams. Treats general problems of seismologic engineering, particularly the origin and tectonic mechanisms of natural and induced earthquakes, and outlines procedures for determining dynamic loadings and evaluating the seismic response and risk of dams.

Book Description
The present volume provides a comprehensive understanding of the modern criteria, models and methods of analysis of arch dams, for normal operation conditions and under exceptional loads. This information is important for all those involved in the evaluation of the behaviour and condition of arch dams and other large structures, either for design or monitoring purpose.

Book Description
The consequences of a large dam failing can be disastrous. However, predicting the performance of concrete dams during earthquakes is one of the most complex and challenging problems in structural dynamics. Based on a nonlinear approach, Seismic Safety Evaluation of Concrete Dams allows engineers to build models that account for nonlinear phenomena such as vertical joint slippage, cracks, and cavitation. This yields more accurate estimates. Advanced but readable, this book is the culmination of the work carried out by Tsinghua University Research Group on Earthquake Resistance on Dams over the last two decades. Nonlinearity characteristics of high concrete dams, seismic analysis methods, evaluation models A systematic approach to nonlinear analysis and seismic safety evaluation of concrete dams Includes nonlinear fracture of dam-water-foundation interaction system, dynamic fluid-structure Covers soil-structure interactions, and meso-scale mechanical behavior of concrete are all international front issues of the field

Book Description
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.
