Abstract
Maximum moduli are the primary parameter in the determination of wave velocities in soils. They can be evaluated from either laboratory or field testing. In general, the excitation loadings used in laboratory and field testing are different. The resonant column apparatus was used to study the effect of loading type on the maximum moduli of sands. Sinusoidal, random and impulse loading were used. Sand specimens were tested either longitudinally or torsionally with one of the three types of loading at low strain levels, and the low-amplitude moduli were measured. Maximum moduli of the specimens were obtained from the low-amplitude moduli. It was concluded that loading type has no effect on the maximum moduli of soils. Also, the maximum moduli at different confining pressures agreed well with published equations.
