In order to study the effect of multi-support excitation of Earthquake Ground Motion on the seismic response of embankment dams, the dynamic response of the Masjed Soleiman earth dam is analyzed. In this research, the Spatially Variation of Earthquake Ground Motion (SVEGM) is introduced by ten different models. Consequently, the stochastic SVEGM model which accounts for both incoherence and wave passage effects is used to specify the non-uniform earthquake excitation. Based on the analysis results, the normal and shear stress distributions as well as the shear strain distribution and their maximum values on the dam body were estimated. Totally, the results of this research indicate that the distribution of stresses, strains and displacement in upstream-downstream direction of dam body increase by increasing the non- uniformity of the input excitation. This increment, which is depended to the number of uniform zone and is independent from the different coherency models, is almost between 50-180 per cent.
