Today to design large hydraulic structures like dams, application of dynamic analysis in time domain seems very interesting due to its benefits. For applying such analysis, appropriate earthquake records that are compatible to site conditions are necessary for designer. Such information is rarely recorded for a dam site during an earthquake and usually the amount of recorded data is not suffici...
