| Abstract: | The scaled boundary finite element method(SBFEM) was extended to transient coupling analyses of the dam-reservoir interaction,and a SBFEM and finite element method(FEM) coupling formulation was derived.Through using the coupling terms in the coupling formulation,a decoupling iteration algorithm was developed to analyze the transient responses of vertical dam and gravity dam-reservoir systems subjected to horizontal ground shock excitations,where FEM was chosen to model finite domain,while SBFEM was applied ... |
