Studying effects due to pile driving on free domain vibrational response using lumped mass model

Abstract

    In this paper, lumped mass model is used to study the effect due to pile driving on ground response in the vicinity. This is a popular problem in structural dynamics, however, one issue is how to reduce time elapsed for soil behavior computation with a good enough accuracy of prediction. The major objective of this study is to find out the peak particle displacement, velocity and acceleration in the far field ground during pile driving, using lumped mass method and linear elastic soil model. The numerical results including displacement, velocity and acceleration showed a good match as compared with that from finite element method by Plaxis.
