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.

Book Description
A comprehensive guide to modern-day methods for earthquake engineering of concrete dams Earthquake analysis and design of concrete dams has progressed from static force methods based on seismic coefficients to modern procedures that are based on the dynamics of dam–water–foundation systems. Earthquake Engineering for Concrete Dams offers a comprehensive, integrated view of this progress over the last fifty years. The book offers an understanding of the limitations of the various methods of dynamic analysis used in practice and develops modern methods that overcome these limitations. This important book: Develops procedures for dynamic analysis of two-dimensional and three-dimensional models of concrete dams Identifies system parameters that influence their response Demonstrates the effects of dam–water–foundation interaction on earthquake response Identifies factors that must be included in earthquake analysis of concrete dams Examines design earthquakes as defined by various regulatory bodies and organizations Presents modern methods for establishing design spectra and selecting ground motions Illustrates application of dynamic analysis procedures to the design of new dams and safety evaluation of existing dams. Written for graduate students, researchers, and professional engineers, Earthquake Engineering for Concrete Dams offers a comprehensive view of the current procedures and methods for seismic analysis, design, and safety evaluation of concrete dams.

Book Description
A mathematical model is proposed for the mechanical properties -- constitutive relation and strength -- of concrete subject to dynamic cyclic reversible stresses and strains that may occur in gravity dams subjected to earthquake ground motion. The model describes properties of concrete under a two-dimensional state of stress. The effects of strain rate -- the time rate of change of strain -- on the mechanical properties are incorporated in the model. Experimental results available in the literature form the basis for the proposed model. A method is developed for nonlinear analysis of response of concrete gravity dams to earthquake ground motion wherein mechanical properties of concrete are defined by the mathematical model mentioned above. Earthquake analyses reveal that cracking of concrete is confined to areas near the upstream and downstream faces of dams -- especially in the upper parts and in some cases also near the heel. The estimated cracking is very sensitive to the assumed tensile strength.

Book Description
With the development of civilization of mankind, dams engineering came into existence to fulfilled the requirements of drinking water, irrigation purpose and flood control and with advancement of technology dams became the prime sources of production of electricity. Although technology get advanced but lots of cases of dam failure occur in the past due to earthquake and consequently losses of life. So it becomes necessary to developed earthquake resistance dam for strong ground motion. In this book after discussion of different methods, finite element method is adopt for the analysis of dam. A strong ground motion has been chosen for the analysis of earthen dam considering nonlinearity of the material. The complete analysis of dam undergoes various steps like slope stability, seepage, pore water pressure, stress-strain and deformation analyses for static and dynamics loads. The results and effects of nonlinearity discussed in details.
