Vibration amplitudes in the Inuvik powerhouse
Vibration measurements in the main powerhouse at Inuvik, NWT, were taken to determine the amplitudes of vibration present in a structure supported on pile foundations in permafrost and subjected to large dynamic periodic forces. Accelerometers were placed on the support system for the main diesel ge...
