| Type and height of foundations of embankment dam are among the factors affecting their seismic response. Various kinds, heights and other conditions of the foundation play fundamental roles in transmitting, attenuating or amplifying seismic waves. Considering 6 different Shear Stiffness and 7 different heights for the Mashkid Olia dam foundation, this study investigated the effect of Shear Stiffness and Height of the foundation on the seismic behavior of the dam through equivalent linear method using the software package of Geostudio (version 2007) and scaled accelerograms of Northridge and Elcentro earthquakes. Results of dynamic analysis as graphs representing changes in shear stresses and strains on the central axis of the dam and the way of changes in acceleration along the vertical axis of the dam are obtained using two accelerograms. Obtained results show the undeniable effect of conditions and Height of foundation on the seismic behavior of the embankment dam.
