Abstract
Behaviour of laterally loaded piles is studied treating the soil medium as an elastoplastic medium. In the elastic range, the foundation reaction is incorporated in the analysis using the Winkler's hypothesis, while in the plastic range yield pressure of the soil is considered. Solutions are obtained treating the pile as a beam on elasto-plastic foundation. Different cases of boundary conditions of the pile are considered. The response of the pile is obtained in terms of dimensionless parameters and are presented in the form of figures. Results show a good agreement with the observed behaviour.
