The dynamic characteristics of a hollow steel pile are examined in the current investigation under rotating machine-induced lateral excitations. To achieve this objective, dynamic field tests are conducted on a single pipe with a length of 3.0 m and a thickness of 0.003 m that is driven into clayey silt soil using a SPT hammer setup. For different excitation forces and static loads, the frequency-amplitude responses of the soil-pile setup are measured. Two distinct resonant peaks are found at two different frequencies during field tests under the operating range of a DC motor, where the first resonant peaks are found to dominate as compared to the second peaks. The numerical analysis is also carried out by DYNA software using continuum-based solutions to investigate the measured response characteristics under both linear and nonlinear conditions. From the comparison between field and numerical results, it is observed that the numerical responses obtained with linear analysis predicted a lower value of resonant amplitudes and a higher value of resonant frequencies as compared to the experimental results. However, the predicted responses from nonlinear analysis indicate a well-matched solution with field results. In this analysis, such agreement is achieved with the consideration of precise values of boundary zones and separation lengths. Both field and predicted response curves of the single pile setup display nonlinearity as the resonant frequencies decrease with an increase in excitation forces, and the variation of amplitudes is found to be disproportional to the excitation forces. The results also show that the resonant amplitudes and frequencies for both the first and second peaks decrease with the increase of static loads under lateral excitations.
