Comparative Analysis of Piles under Change in Variables using Plaxis 2D

The past two decades have seen a remarkable increase in the rate of construction of high-rise buildings or other civil structures which produce excessive loads, excessive settlements and differential settlements. As a solution to the settlement problem of high-rise buildings, many designers use pile foundation design by considering different number of piles, length of the pile and diameter of the piles. In this paper a pile foundation for a large multi storey building (G+14) is studied as a case study. Analysis of total settlement, pile settlement, axial force and bending moment within piles under change in variables such as diameter, spacing and length of pile using finite element method (FEM) tool Plaxis 2D is calculated. Finally, the behavior of piled w.r.t effect of diameter of piles, spacing between piles, and length of pile on total settlement, pile settlement, axial force and bending moment of pile foundation system are assessed and conclusions are made
