Fundamental Mode Response of Dams Including Dam–Water Interaction
The motions of a dam during an earthquake cause dynamic pressures in the impounded water that act on the upstream face of the dam to modify the dam motions, which in turn influence the hydrodynamic pressures. This chapter considers this interaction between the dam and water. Considering only the fundamental mode of vibration of the dam, the chapter first presents a procedure for analysis of dam response including dam–water interaction. It then presents the results for hydrodynamic pressures on the upstream face of the dam for two cases: a rigid dam excited by x and y components of ground motion; and a flexible dam undergoing motion in its first mode of vibration. Finally, the chapter provides an equivalent single‐degree‐of‐freedom system to model the response of dams including dam‐water interaction that enables estimation of peak response directly from the earthquake response (or design) spectrum.
