dc.description.abstractKenyir Dam located in Terengganu, Malaysia is a hydropower dam which served the purpose of generating electricity to the surrounding areas. Water is basically flown from the upstream to downstream area through the intake and pressure tunnel sections. In some cases, due to large volume of water, the dam structure might experience significant vibration effect from water spill event. In this study, the flow-induced vibration during critical water spilling of 148�m water level at intake section of Kenyir Dam is investigated using ANSYS software. The results from both frequency domain and operational deflection shapes (ODS) are compared with the natural frequencies and mode shapes of the dam, in order to determine the safety precautions during dam operating condition. From the results of water level 148�m, the transient vibration response from the water flow is occurred at operating frequency of 2.745�Hz. There is no resonance phenomenon during this water spilling condition since the natural frequency of the intake section occurred at 3.5�Hz. However, some precautions should be taken since the deflection shapes of the dam structure might be higher above this water level. ?
