Investigation of Uplift force effects on Seismic Damage of Concrete Gravity Dam in the Near-Fault and Far-Fault Ground Motions:Case Study Shafaroud Dam

Uplift force has significant role on dynamic response of concrete gravity dams and also seismic response of dams in near field motion can be considerably different from those observed in the far field and the near –fault ground motions can cause considerable damage during an earthquake.
