Time‐Domain Analyses of Dam‐Reservoir System. II: Substructure Method

Abstract

Nonlinear analyses of (flexible) dam‐ (infinite) reservoir interactions require time‐domain formulations. In this paper, an exact consideration of radiation condition in the far field of the infinite reservoir and a time‐domain substructure method are presented. The proposed method can explicitly express the physical phenomena of the dam‐reservoir system. Results obtained compared very well with available exact solutions for simple geometries. Additional results with arbitrary geometrical shapes are also presented to illustrate the applicability of the method.
