A Study On Soil-Structure Interaction Of Free-Standing Pile Group Foundation Using Finite Element Analysis By Using “Ansys” Software And Results Comparing With Pile Load Test “Is : 2911”.

Abstract

This paper research explained about “SOIL-STRUCTURE INTERACTION OF FREE-STANDING PILE GROUP FOUNDATION USING FINITE ELEMENT ANALYSIS BY USING “ANSYS” SOFTWARE. Analysis of free-standing pile group foundation has been carried out by using finite element method to evaluate the deflection & deformations developed under structural load conditions and compare the results with IS: 2911(Part :4) Pile load test. Pile group foundation in sand medium by considering constant pile diameter, having different spacing of pile and having different pile length with different loading combinations. The model consist of sand medium of 100m x100m x 50m is considered and pile group (1x2) in the surrounding soil with end bearing piles are considered. The diameter of RCC pile assumed as (d) 1.0m, Length of pile is ”l/d = 10 & 20”, Spacing of pile is “s/d= 3 & 4” for Model-I  & model -II respectively and thin raft assumed as 6m x3m x 0.75m which is placed above 0.5m from natural ground level. Two different models with two different loading condition such as Moment only applied and Force + Moment are applied as added in different cases too.
