Hydrodynamic pressures on dams during earthquakes
Intensity, distribution, and frequency characteristics of hydrodynamic pressures acting on dams during earthquakes are discussed; short review of previous work on this subject is presented; general expressions for complete time history of pressures during arbitrary horizontal and vertical ground motions are derived; it is concluded that concept of added mass, moving with dam, to represent hydrodynamic effects is not valid for earthquake-type excitations; it is also shown that significant errors are introduced by ignoring compressibility of water; standard design practice in considering additional water pressures on dams due to earthquakes is compared with theoretical responses.
