the effect of the spatial variation of earthquake ground motion SVEGM on dynamic response of multiple -support structures can be important. The objective of this paper is to investigate the stiochastic seismic response of an embankment dam subjected to multiple-support excitation . to this end the response of marun embankment dam to uniform and non-uniform excitations were analyzed using a random vibration approach . the spatially varying ground motion is modelled considering both imcoherence and wave passage effects.
