Flexural responses of grouped piles under dynamic loading

Abstract A simple approach to analyse the flexural vibration of grouped piles was developed. In this approach, a pile group is replaced by a single pile for the evaluation of the pile‐head flexibility matrix. Parametric studies were conducted for various conditions of grouped piles. Various features of flexural vibration of pile groups were found. The charts presented in this paper enable quick estimations of dynamic group effects to be made in a manner similar to that widely used for the evaluation of static group effects.
