Abstract

Cohesive soils at different confining pressures were tested in a resonant column device using both impulse and random torsional excitation in addition to conventional sinusoidal excitation. The damping and shear modulus from both impulse and random loadings were determined by both the power spectral density function and the transfer function methods. Evaluation of the dynamic soil properties for sinusoidal vibration followed conventional procedures. The results indicated that during impulse and random loadings the damping values were higher and the shear moduli lower than the values obtained from sinusoidal loading at the same root mean square strain.
