Abstract
Cyclic drained simple shear tests on a dry sand using a 12 in diameter sample with sample heights of 1, 2, and 4 in show the effect of Diameter/Height ratio on the shear modulus and percent of critical hysteretic damping at various shear strain levels. The shear modulus is found to increase with cycle number and with increasing specimen size. The D/H ratio is found to affect the shear modulus at low shear strains (< 1 percent) and found to have little effect at higher shear strains and at failure. The hysteretic damping decreases for all values of shear strain tested (0.01 to 1 percent) as the cycle number and D/H ratio increases. Possible implications on design and pore pressure development are mentioned.
