NUMERICAL ANALYSIS OF THE BEHAVIOUR OF A FLEXIBLE PILE FOUNDATION VERSUS A RIGID ONE UNDER LATERAL CYCLIC ACTION
Abstract
The purpose of the present paper is to analyse the behaviour of a flexible pile foundation versus a rigid one when submitted to lateral cyclic action coming from waves or wind, through numerical modelling using 3D finite elements. The comparison elements are: the maximum pile head displacement and the evolution of the maximum bending moment. The numerical modelling has been performed using the software CESAR-LCPC [1]. The study has been performed for 15 cycles, but the numerical model has also served to create some extrapolation functions allowing the analysis of a high number of cycles ? up to 100000. The numerical model has been initially calibrated using the results of some small-scale centrifuge experimental tests performed by Frederic Rosquo?t [2], officially obtained from IFSTTAR, Nantes [3]. The experimental results used for calibrating the numerical model were performed for a flexible pile. After that, on the calibrated model, the flexible pile has been changed into a rigid one and a comparison between them regarding the behaviour under lateral cyclic action has been performed.
