Abstract
This paper presents a theoretical analysis for the hydrodynamic pressure induced by the rotating vibration of the skinplate of Tainter gates on Folsom dam in California. The curved skinplate and dam crest were replaced by the straight line to simplify the flow boundary. The reservoir flow fluctuation induced by the skinplate vibration with a small amplitude was analyzed for the zero gate-opening, by a potential flow theory developed for dissipative wave radiation problems. Thus, the hydrodynamic pressure exerted on the skinplate was derived in a non-dimensional expression, and its major characteristics were revealed.
