چکیده مقاله:
Hydrodynamic pressure distribution on upstream face of the dam depends on several parameters such as distance hom fault, natural frequency of dam and etc. distance from fault cause significant eff ect on amplitude and frequency content of the motions. Frequency contents could cause significant effects on dam responses and hydrodynamic pressure distribution which is main goal of this paper. In hydrodynamic pressure fluctuations, sub-pressu.re occurrence cause cavitation problem on upstream face of the dam.Although cavitation effects in this case could not cause severe damage on dam body but it is not negligible especially near outlet structures. Results show Bequency contents of the ground motion has a significant effect on hydrodynamic pressure distribution and sub-pressure occurrence.
