In this study the linear dynamic behavior of the Pine Flat concrete dam is applied in the time. problems. However, for a nonlinear analysis of the dam-reservoir system, it is necessary to develop a direct time domain analysis.

A direct time-domain analysis is required when the dam exhibits nonlinear material behavior, for example, under earthquakes. Zienkiewicz and Bettess studied fluid–structure interaction in the time domain using the Sommerfeld radiation condition to approximate the far field. Tsai et al. proposed an accurate implicit semi-analytical transmitting boundary in the time domain. Apr 01, 2011 · A direct time-domain analysis is required when the dam exhibits nonlinear material behavior, for example, under earthquakes. Zienkiewicz and Bettess studied fluid–structure interaction in the time domain by using Sommerfeld radiation condition to approximate the far field. Tsai, Lee and Ketter proposed an accurate implicit semi-analytical transmitting boundary in the time domain. Dynamic Analysis of Dam-Reservoir Interaction in Time Domain. Impedance option is used as boundary condition of absorbent of reservoir and wave. For each software, time history analysis of pressure and displacement are done and finally suitable elements for dam structure and reservoir fluid are introduced comparing the results obtained. Preface Mostexisting arch dams have been designed for seismic loading by static methods involving the use of seismic coe cients. Although there are no known examples of arch dams. The dam-reservoir system is divided into the near field modeled by the finite element method, and the far field modeled by the excellent high-order doubly asymptotic open boundary DAOB. Direct and partitioned coupled methods are developed for the analysis of dam-reservoir system. In the direct coupled method, a symmetric monolithic governing equation is formulated by incorporating the DAOB.

Absorbing Boundaries for the Time-Domain Analysis of Dam-Reservoir-Foundation Systems: Glauco Feltrin: November 1997. Rational Transmitting Boundaries for Time-Domain Analysis of Dam-Reservoir Interaction:. Institut für Baustatik und Konstruktion ETHZ November 1978. An explicit time‐domain transmitting boundary for the analysis of dam‐reservoir interactions is presented. This transmitting boundary is a semi‐analytical solution of the governing wave equation of the far field of the reservoir. By using this transmitting boundary, the radiation condition and water compressibility can readily be incorporated in the time‐domain analysis of dam.

In this paper, time domain transient analysis of dam-reservoir interaction is studied. Resulting hydrodynamic pressure is exactly calculated including the effect of vertical component of earthquake acceleration as well as the horizontal component. Method of separation of variables is applied to solve resulting partial differential equation after applying Laplace transform.

The scaled boundary finite element method SBFEM was extended to solve dam-reservoir interaction problems in the time domain and a dynamic stiffness used in the SBFEM of semi-infinite reservoir in the time domain was proposed, which was evaluated by the Bessel function. Based on the dynamic stiffness, transient responses subjected to horizontal ground motions were analyzed through coupling.

  1. 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.

This phenomenon is termed dynamic dam–reservoir interaction DRI and it could be catastrophic in cases of resonance, that is when the two domains dam and reservoir are vibrating in phase. There are numerous studies related to the numerical modeling of DRI in which the reservoir domain is discretized and included in the analysis. one given by Rashed1983, who presented dam-reservoir interaction results for 2D and 3D prob-lems. Lee and Tsai 1991 developed a closed form time domain analysis using a simplified geometry of the monolith. The common point of all the works cited above is the wave equation governing the fluid domain. suitable for the seismic analysis of concrete gravity dam; 2 the sediment at reservoir bottom has a significant effect on the seismic response of the concrete gravity dams. Maity. D. 2005 4 Maity, in his work studied the coupled response of the dam-reservoir system is studied under earthquake load using the time domain approach. The model consists of an incompressible water mass attached in series to a damper. The latter is fixed to the upstream face of the dam. The overall trends of the exact analytical solution are duplicated over the whole frequency range. This approximate model can thus be used directly in a time-domain analysis.
