Theoretical Interpretation and Consideration on Interaction between A Dam and Its Foundation in Dynamic Analysis of Dams

Abstract

Dynamic analysis of a dam is generally conducted including its foundation in the seismic design of dams. In the analysis, the acceleration of the base of foundation is calculated in the foundation model without a dam, and this base acceleration is applied in the whole structural system of a dam and foundation. The paper discussed the interpretation and consideration on this pullback procedure. In addition, the remark of the analysis was discussed.
