Abstract

The calculations of transient hydrodynamic forces acting on dams subjected to arbitrary earthquakes are considered. A simple computational method based on the unit force hydrograph and the principle of linear superposition is proposed. The unit force hydrograph is calculated from analytic solution of a unit earthquake with a unit duration. Two test examples of earthquakes, one a linear earthquake with a finite duration and the other the EL Centro earthquake, are considered. The present results are compared with other analytic hydrodynamic solutions, and the comparisons show that the present computational method can predict very well the hydrodynamic forces acting on dams.
