Time-domain analyses of dam-reservoir system. II: Substructure method

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.
