Earth­quake analy­sis of dams pro­vide an added chal­lenge be­yond analy­sis of soil-struc­ture sys­tems be­cause here there are two un­bound­ed do­mains — the wa­ter and the foun­da­tion rock, in­ter­act­ing with each oth­er as well as the dam — as op­posed to on­ly one un­bound­ed do­main in soil-struc­ture in­ter­ac­tion.

We show next how the the­o­ry of ef­fec­tive seis­mic in­put for soil-struc­ture in­ter­ac­tion is ex­tend­ed to the earth­quake analy­sis of dams, and how the ex­ist­ing im­ple­men­ta­tion in LS-DY­NA is re­pur­posed for such analy­sis.
