Intake tower of Doosti dam located at Iran-Turkmenistan border has been modeled with water of surrounding reservoir in ANSYS software, to investigate linear seismic responses due to Naghan, Tabas and Elcentro earthquakes records. Results obtained from over than 20 seismic analyses show that the seismic response of intake tower, hydrodynamic pressure distribution pattern, shear force and bending moment distribution at height and first principal stress strongly depend on the type of modeling, type of excitation and the time of maximum top response.
