Summary : 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 and Covers soil-structure interactions, and meso-scale mechanical behavior of concrete are all international front issues of the field.

Summary : The hazard posed by large dams has long been known. Although no concrete dam has failed as a result of earthquake activity, there have been instances of significant damage. Concerns about the seismic safety of concrete dams have been growing recently because the population at risk in locations downstream of major dams continues to expand and because the seismic design concepts in use at the time most existing dams were built were inadequate. In this book, the committee evaluates current knowledge about the earthquake performance of concrete dams, including procedures for investigating the seismic safety of such structures. Earthquake Engineering for Concrete Dams specifically informs researchers about state-of-the-art earthquake analysis of concrete dams and identifies subject areas where additional knowledge is needed.

Summary : The development of water resources is a key element in the socio-economic development of many regions in the world. Water availability and rainfall are unequally distributed both in space and time, so dams play a vital role, there being few viable alternatives for storing water. Dams hold a prime place in satisfying the ever-increasing demand for power, irrigation and drinking water, for protection of man, property and environment from catastrophic floods, and for regulating the flow of rivers. Dams have contributed to the development of civilization for over 2,000 years. Worldwide there are some 45,000 large dams listed by ICOLD, which have a height over 15 meters. Today, in western countries, where most of the water resources have been developed, the safety of the existing dams and measures for extending their economical life are of prime concern. In developing countries the focus is on the construction of new dams. The proceedings of the 4th International Conference on Dam Engineering includes contributions from 18 countries, and provides an overview of the state-of-the-art in hydropower development, new type dams, new materials and new technologies, dam and environment. Traditional areas, such as concrete dams and embankment dams, methods of analysis and design of dams, dam foundation, seismic analysis, design and safety, stability of dam and slope, dam safety monitoring and instrumentation, dam maintenance, and rehabilitation and heightening are also considered. The book is of special interest to scientists, researchers, engineers, and students working in dam engineering, dam design, hydropower development, environmental engineering, and structural hydraulics.

Summary : Validation of Dynamic Analyses of Dams and Their Equipment is the outcome of a three year cooperation program between CFBR (Comite Francais des Barrages et Reservoirs or French Committee on Large dams) and JCOLD (Japan Commission on Large Dams), and focusses on the dynamic behavior of concrete and embankment dams analyzed based on acceleration records of the JCOLD data base. The book covers a broad range of topics, including simplified and detailed methods of dynamic analysis for the seismic response of concrete and embankment dams compared with measured behavior. The response of embankment dams subjected to a 1.0 g foundation acceleration time history is computed by several analytical methods and compared. The modelling of stress-strain behavior of compacted soils for seismic stability analysis of earth-fill dams and its application for a failed earthfill dam is described. The cracking of the face slab of four faced rockfill dams during earthquakes is analyzed. The seismic behavior of concrete arch dams is discussed by the comparison of numerical and experimental results. Displacement-based seismic assessment of concrete dams is presented. Finally the book contains a comparison between the Japanese and French design criteria of gates and a comparison of the analysis of gates and field measurements. Validation of Dynamic Analyses of Dams and Their Equipment will be useful to professional and academics involved or interested in dam engineering.

Summary : This reference book presents the theory and methodology to conduct a finite element assessment of concrete structures subjected to chemically induced volumetric expansion in general and alkali aggregate reaction in particular. It is limited to models developed by the author, and focuses on how to best address a simple question: if a structure suffers from AAR, how is its structural integrity jeopardized, and when would the reaction end. Subjects treated are: • Brief overview of AAR: nature of the chemical reactions, AAR in both dams and nuclear power plants, and how does it impact the mechanical properties of concrete. • Constitutive model for both the AAR expansion, and concrete nonlinearities (both smeared and discrete crack models). • Validation of the model along with a parametric study to assess what are the critical parameters in a study. • Selection of material properties for an AAR finite element simulation, followed by applications in dams and massive reinforced concrete structures. • Micro Model for improved understanding of the essence of the reaction, along with a newly proposed mathematical model for the kinetics of the reaction. • Review of relevant procedures to estimate the residual expansion of a structure suffering from AAR, along with a proposed approach to determine when the reaction will end. The book is extensively illustrated with numerous figures and provides guidance to engineers confronted with swelling in concrete infrastructures.
