Seismic Safety Analysis of Arch Dams: Fact or Fiction?
Abstract
The state of the art of finite element procedures for evaluating the earthquake response of arch dams is presented. taking account of the interaction of the dam with it. foundation rock and reservoir water. The
generally good performance of current procedures is demonstrated by correlation of analytical results with measured data from forced vibration field tests. It is pointed out, however, that these analytical procedures
may not be equally effective in predicting the response of arch dams to earthquake input. Deficiencies of the standard seismic input mechanism are discussed. and several improved procedures are descrlbed, but further research is required before final conclusions may be drawn.
