Abstract
Accurate prediction of earthquake response of a dam is necessary for reliable evaluation of safety of the dam. In the computation, appropriate numerical modeling should be done to get trustworthy results, and it is important to validate the modeling of dams by comparing computed results with observed ones. In this paper, the response of Hitokura concrete gravity dam to the 1995 Hyougoken-Nanbu Earthquake is simulated by using a computer code developed for the analyses of two dimensional dam-foundation rock-reservoir water interaction. Extensive finite element studies are conducted, and the results are compared with recorded responses. Appropriate material properties of dam and foundation rock to be used in the analysis and a rational procedure to determine them are discussed.
