On Prediction of Dynamic Pile Behavior
Abstract
There are several models to predict response of single pile and pile groups. the lateral dynamic response of a single pile predicted by analytical models often yields higher natural frequencies and lower resonant amplitudes than those determined in field tests. This has been related to overestimated soil's shear modulus and radiation damping used in the calculations of the response. a simplified method was recently proposed to calculate strain dependent reduction factors for shear modulus and damping which were used for prediction of pile response. the reduction factors were developed based on reported pile test data at one site. the pile performance for another different site for which for which test results are available was calculated and compared with the observed pile response. in addition a comparison of the predicted pile response has been made with observed pile response during the full scale pile tests conducted by the authors. Results of these comparisons based on limited test results are presented. Copyright © (2010) by Earthquake Engineering Research Institute.
