Available in PDF, EPUB and Kindle. Book excerpt: Vibration tests were conducted on a 1:24-scale model of the North Fork Dam (Near Auburn, Calif.), a double-curvature arch dam, to determine natural frequencies, mode shapes, and hydrodynamic pressures. The mode shapes, natural frequencies, and hydrodynamic pressures were determined from tests using two-vibrators mounted on the crest of the dam. Hydrodynamic pressures at the dam-reservoir interface were also determined from tests in which the vibrator was attached to the downstream foundation of the dam. The hydrodynamic pressures calculated using Westergaard;s theory and a theory for arch dams developed by Perumalswami and Kar accurately predicted the measured pressure at frequencies below the first mode frequency of the dam. The differences in the two theories were insignificant. The accuracy of the Ritz analysis improved considerably as more nodes in flexible regions of the dam were loaded. However, the lowest eigenvalues were computed using the subspace iteration method. For the full reservoir, the natural frequencies decreased by 20-30% when the foundation was included in the finite element model. The difference was less when the reservoir was empty. The calculations using the subspace iteration scheme and including the foundation agreed closely with experimental mode shapes and corresponding natural frequencies.
Book Synopsis Earthquake Response of Concrete Gravity Dams Including Hydrodynamic and Foundation Interaction Effects by : Anil K. Chopra
Download or read book Earthquake Response of Concrete Gravity Dams Including Hydrodynamic and Foundation Interaction Effects written by Anil K. Chopra and published by . This book was released on 1980 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: A general procedure for analysis of the response of concrete gravity dams, including the dynamic effects of impounded water and flexible foundation rock, to the transverse (horizontal) and vertical components of earthquake ground motion is presented. The problem is reduced to one in two dimensions, considering the transverse vibration of a monolith of the dam. The system is analyzed under the assumption of linear behavior for the concrete, foundation rock and water. The complete system is considered as composed of three substructures -- the dam, represented as a finite element system, the fluid domain, as a continuum of infinite length in the upstream direction, and the foundation rock region as a viscoelastic halfplane. The structural displacements of the dam are expressed as a linear combination of Ritz vectors, chosen as normal modes of an associated undamped dam-foundation system. The effectiveness of this analytical formulation lies in its being able to produce excellent results by considering only a few Ritz vectors. The modal displacements due to earthquake motion are computed by synthesizing their complex frequency responses using Fast Fourier Transform procedures. The stress responses are calculated from the modal displacements. An example analysis is presented to illustrate results obtained from this analytical procedure. Computation times for several analyses are presented to illustrate effectiveness of the procedure.

Book Synopsis Seismic Performance Analysis of Concrete Gravity Dams by : Gaohui Wang
Download or read book Seismic Performance Analysis of Concrete Gravity Dams written by Gaohui Wang and published by Springer Nature. This book was released on 2020-07-10 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Seismic Safety Evaluation of Concrete Dams by : Chong Zhang
Download or read book Seismic Safety Evaluation of Concrete Dams written by Chong Zhang and published by Elsevier. This book was released on 2014-10-23 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis A Computer Program for Earthquake Analysis of Gravity Dams Including Hydrodynamic Interaction by : P. Chakrabarti
Download or read book A Computer Program for Earthquake Analysis of Gravity Dams Including Hydrodynamic Interaction written by P. Chakrabarti and published by . This book was released on 1973 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer program for earthquake analysis of gravity dams including effects of hydrodynamic interaction is presented. The dam-water system is idealized as two-dimensional in geometry, the material behavior is assumed to be linearly elastic, and the transverse horizontal as well as the vertical component of ground motion are considered. The dam is represented as a finite element system, whereas water in the reservoir is treated as a continum of infinite length in the upstream direction governed by the wave equation. Compressibility of water is considered resulting in governing equations for the dam depending on the excitation frequency. The analysis is performed in the frequency domain, first obtaining the frequency responses and then Fourier Synthesizing them by Fast Fourier Transform procedures to obtain responses to arbitrary ground motion. A listing of the computer program is included and the usage and capabilities are illustrated by examples. (Author).

Book Synopsis Earthquake Analysis and Design of Industrial Structures and Infra-structures by : Indrajit Chowdhury
Download or read book Earthquake Analysis and Design of Industrial Structures and Infra-structures written by Indrajit Chowdhury and published by Springer. This book was released on 2018-10-06 with total page 1050 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite significant development in earthquake analysis and design in the last 50 years or more, different structures related to industry, infra structure and human habitats get destroyed with monotonic regularity under strong motion earthquake. Even the recent earthquake in Mexico in September 2017 killed a number of people and destroyed national assets amounting to hundreds of millions of dollars. Careful evaluation of the technology reveals that, despite significant development in earthquake engineering, most of the books that are available on the market for reference are primarily focused towards buildings and framed type structures. It is accepted that during an earthquake it is buildings that get destroyed most and has been the biggest killers of human life. Yet, there are a number of structures like retaining walls, water tanks, Bunkers, silos, tall chimneys, bridge piers etc that are equally susceptible to earthquake, and if damaged can cause serious trouble and great economic distress. Unfortunately, many of these systems are analyzed by techniques that are too simplified, unrealistic/obsolete or nothing is done about them, ignoring completely the seismic effects, as no guidelines exist for their analysis/design (like seismic analysis of counterfort retaining walls or dynamic pressures on bunker walls etc.). This highly informative book addresses many of these items for which there exists a significant gap in technology and yet remain an important life line of considerable commercial significance.The book is an outcome of authors' academic research and practice across the four continents (USA, Europe, Africa and Asia) in the last thirty two years, where many of these technologies have been put in practice, that got tested against real time earthquakes. All methods presented herein have been published previously in peer reviewed research journals and international conferences of repute before being put to practice. Professionals working in international EPC and consulting engineering firms, graduates taking advanced courses in earthquake engineering, doctoral scholars pursuing research in earthquake engineering in the area of dynamic soil structure interaction (DSSI) and advanced under graduates wanting to self-learn and update themselves on earthquake analysis and design are greatly benefited from this book.

Download or read book Validation of Dynamic Analyses of Dams and Their Equipment written by Jean-Jacques Fry and published by CRC Press. This book was released on 2018-06-27 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
