Abstract
A cantilevered pile, flexible only in the transverse direction, has been submitted to wave action. It has been found that resonance transverse vibrations, with natural frequency fn, are induced by eddies shedding in waves having frequency fw = 1, 1/2, 1/3, 1/4 fn. A lock-in effect has been observed within the range of 0.9 fn ≤ fw ≤ 1.1 fn. Results of a simple mathematical model find reasonable support in the experiments.
