Abstract Recorded ground accelerations at various locations of Karun III Dam during November 20, 2007, were recorded by an array accelerometers located on the dam. In terms amplitude and phase, these show non-uniformities in different elevations. this paper, effect non-uniform motions seismic response dam taking dam-reservoir-foundation interaction into account is investigated. The EACD-3D-2008...

The Jackson Lake Dam was constructed in 1917 in the Grand Teton National Park near Jackson, Wyoming. The dam was a hydraulic fill placed on a natural alluvium and outwash foundation. The Bureau of Reclamation (Burec) determined that the dam and its foundation would be susceptible to liquefaction and failure during a potential earthquake; a series of contracts was let to remove and replace the d...

Unbalanced forces developed by hammer wear and impact must be resisted by auto shredder foundations. Methods for estimating the impact forces are described. Because of different soil conditions, a concrete mat, a concrete block, and a pile.supported foundation system were adopted at three different construction sites. The design procedures involved in determining the dynamic response for each t...

Current formulas for calculating scour depth below of a free over fall are mostly deterministic in nature and do not adequately consider the uncertainties of various scouring parameters. A reliability-based assessment of scour, taking into account uncertainties of parameters and coefficients involved, should be performed. This paper studies the reliability of a dam foundation under the threat o...

SUMMARY No RCC dams have been built in Germany to date. HRB Waldbärenburg could be the first one. This project is part of the national flood control programme of the Federal State of Saxony in Germany and will go into the approval procedure at the end of 2012. The RCC dam technology has been chosen as it provides environmental advantages against other design alternatives: essential lower impact...

Because of different behavior of reservoir water and dam material, the determination of hydrodynamic pressure during earthquake is very complicated. Thus, different formulations have been presented for modeling of the dam reservoir system under dynamic loading such as earthquake. These formulations can be categorized into two general groups, which are Lagrangian and Eulerian, each having advant...
