Numerical Modelling of Laterally Loaded Single Pile.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
Design of piles under lateral loads requires not only estimation of ultimate load carrying capacity of the pile but also, the pile deflections need to be evaluated to determine the allowable loads. There are many approaches to estimate the lateral capacity of piles. Among them,
IS code method is invariably used by engineers in our country. Numerical modelling using finite element (PLAXIS-3D) software is the advanced method to analyze piles in which all sorts of non-linearity could be modeled. The present work is done separately for sands and clays. First, a laterally loaded pile in homogenous sand is considered. Pile responses of single pile for various loadings obtained from the above three methods are compared and analyzed. As there are large differences in maximum lateral deformations obtained from IS code method, sub grade reaction method when compared to numerical modelling there is a need to either modify them or propose a new method. The normalized load-deflection charts using numerical modelling which can be used easily are proposed.
