Book Seismic Performance Analysis of Concrete Gravity Dams

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 Earthquake Response of Concrete Gravity Dams Including Hydrodynamic and Foundation Interaction Effects

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 Earthquake Response of Concrete Gravity Dams

Download or read book Earthquake Response of Concrete Gravity Dams written by Anil K. Chopra and published by . This book was released on 1970 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Includes reservoir interaction effects, the response of concrete gravity dams to horizontal earthquake excitation was investigated and the errors that may be introduced by common simplifying assumptions such as neglecting interaction effects and compressibility of water were evaluated. The problem was simplified to a linear analysis of the two-dimensional vibration of coupled reservoir-dam systems, with the response of the dam being approximated by its deformations in the fundamental mode. Four cases were considered: dam alone (without reservoir), reservoir-dam system -- interaction neglected, reservoir-dam system -- interaction included, and reservoir-dam system -- interaction included but water compressibility neglected. Expressions were derived for the complex frequency response functions for the dam displacement and lateral hydrodynamic force in each of these four cases. These results along with the Fast Fourier Transform algorithm were utilized to compute the time-history of responses of 28 reservoir-dam systems to Taft earthquake. (Author).

Book Earthquake Response of Gravity Dams Including Reservoir Interaction Effects

Download or read book Earthquake Response of Gravity Dams Including Reservoir Interaction Effects written by P. Chakrabarti and published by . This book was released on 1972 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Influence of hydrodynamic interaction on the dynamic behavior of dams is reduced to two dimensions; the material behavior is assumed to be linearly elastic. For analysis in the frequency domain, the system is considered as two substructures: (1) the dam as a finite element system and (2) the reservoir's fluid as a continuum of infinite length upstream governed by the wave equation. The displacements of the dam including hydrodynamic effects are expressed in linear combination of the modes of vibration of the dam with the reservoir empty. The analysis produces exact results if all modes of vibration are included; however it effectively produces excellent results by considering only the first few modes, thus drastically reducing the number of unknowns. Numerical results for complex frequency responses and responses to earthquake ground motions show: (1) hydrodynamic interaction and compressibility of water must be considered to obtain accurate results for the periods of vibration and response to earthquakes, (2) water in the reservoir significantly increases the lateral displacements from earthquake motion; however, the stresses may not increase, depending on the ground motion frequency characteristics, and (3) compared to many classes of structures, the vertical component of ground motion is more important in the response of gravity dams.

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
