Dynamic experiments with small pile foundations

Abstract
Dynamic experiments with small pile foundations were conducted in the field. Individual piles and a group of piles were tested. The experimental data were compared with theoretical predictions made on the basis of a theory described previously by Novak. It was found that the theory predicts the general characteristics of the response very well. Resonant amplitudes and natural frequencies can be predicted reasonably well when a shear modulus of the soil derived from a static test of a pile is used and when a correction for the effect of pile group (interaction) is made.
