Abstract:

In so many cases, the Pile Foundations have largely been integrated, and it’s nearly impossible to imagine the stability of the systems without its application. Pile foundation is used at places where it's difficult to find desired strength of soil at shallow depth like transmission towers, high rise buildings, offshore structures, highways and railways. Pile is designed to bear the vertical load of the superstructure, and in some cases, horizontal loads are generally static in nature. Pile is also subjected to dynamic loads like wave action, wind action, earthquake and vibrations due to heavy machinery. Dynamic analysis is required to study the approximate behaviour of such loads. During an earthquake, i.e., in the case of dynamic lateral loading on the pile, the pile is considered to be a laterally loaded beam, and its bending is governed by the strength of the pile material. The PLAXIS 2D finite element software package was used to observe the pile’s reaction. In addition, piles in the homogeneous medium have been extensively researched, but there is no systematic analysis of the behaviour of piles in the layered deposits that are typically found at the site. The goal of this study is to fill that void. Damping characteristics and local soil properties based on lab results have been incorporated. In particular, the deformation characteristics of the piles under lateral dynamic, as well as the axial loading, have been considered.
