Dynamic Response of 2 Piles in Series and Parallel Arrangement
Keywords:3D finite element analysis, dynamic analysis, Kelvin element, transmitting boundary.
In the present study, dynamic analysis of laterally loaded vertical pile group is carried out by keeping in the mind the three dimensional nature of the soil-pile system. Piles and soil are modelled using three-dimensional finite element techniques treating them as linear elastic. The interface of soil and pile under the lateral load has been accounted for by incorporating interface elements in the modelling. The special type of transmitting boundary using Kelvin element is used to transfer the propagating waves from near field to the far field. Group of two piles in series and parallel configuration have been considered for present study. Individual piles are considered monolithic with pile cap. Parametric studies have been performed to examine the effects of pile spacing and soil modulus on the response of pile group.
