LOAD-DEFORMATION RESPONSE OF SINGLE CORRUGATED PILE IN SOIL MEDIA

Abstract

In the work, 3D numerical modelling and analysis was performed on pile foundation. The numerical modelling and analysis of pile-soil system was accomplished in finite element based software ABAQUS/CAE6.10-1. Also, the analysis was done for corrugated piles of different thicknesses and results were compared. The ratio of pile length to pile diameter was assumed to be 30.The diameter of the pile was taken 0.3 m and correspondingly the length was assumed as 9m. The pile material was taken as steel and soil was assumed to be sandy. ABAQUS defines the contact conditions between two bodies using a master and slave algorithm. In the work, the pile was selected as the master surface and the sand as the slave surface. The meshing density of the pile-soil element contains 1808 nodes and 1162 elements. Vertical compressive loading was applied on the top surface of the pile and outer boundary of the soil was considered fixed. The response of pile foundation was captured under static compressive loading and the vertical deflections were studied considering elastic models of soil and pile. For elastic models of the pile and soil, the Young’s modulus of elasticity and poisson’s ratio were defined in the material property section. The influence of loading on settlement was explored. All the pile models have been embellished assuming an elastic response for the stress-strain relationship within the pile and soil material.
