The Seismic Response of Dams: A Numerical Investigation of the Effect of Shear Stiffness and Height of Embankment Dam Foundation

The type and height of foundations of embankment dams are among the factors affecting their seismic responses. The kinds and heights of these foundations and the other conditions play fundamental roles in transmitting, attenuating, or amplifying the seismic waves. Considering 6 different types of shear stiffness and 7 different heights for Mashkid Olia dam foundation, the effect of shear stiffness and height of the foundation on the seismic behavior of the dam through the equivalent linear method were investigated. It was indicated the undeniable effect of conditions and height of foundation on the seismic behavior of the embankment dam.
