Site response analysis heavily weighs dynamic soil characteristics including liquefaction potential, shear modulus, and soil damping ratio. The current work studies the response of clayey sand owing to dynamic loads. Saturated undrained cyclic triaxial tests have been conducted using strain-controlled loading at different relative densities (50–80%) representing the field conditions and by varying shear strain amplitudes and confining pressure under 1 Hz loading frequency. Test results have shown that soil's ability to liquefy is reduced when confining pressure and relative density increased. For higher shear strains liquefaction susceptibility, damping ratio increased significantly and shear modulus reduced.
