Response Of Saturated Sands To Cyclic Shear At Earthquake Amplitudes, Vincent P. Drnevich, John P. Jent
KWRRI Research Reports
Both quasi-static and resonant cyclic shear tests were performed on hollow cylindrical specimens of saturated sands at various densities and confining stresses. Shear moduli measured at nondestructive amplitudes were shown to be independent of frequency for the range of 0.1Hz to 50Hz. Application of cyclic shear at larger amplitudes caused effective stresses to decrease and failure. The number of cycles to failure was related to ratio of cyclic shear stress to maximum drained shear stress. Effective confining stress reduces approximately linearly with number of cycles. Shear modulus and shear damping.can be described by the Hardin-Drnevich equations if change in effective …
