Soil- Pile Nonlinear Interaction

Present study is carried out the nonlinear interaction of soil-pile and pile cap, study shows the behavior of soil and pile under the working load condition. The 8-story plane frame is constructed using Software ANSYS and a 2D plane of soil and pile is created using Beam188 and Plane 183 element. In this analysis beam-columns are of size 300mm *300 mm and piles are of 400mm having its pile cap of width 2m and thickness of 300mm is considered. Soil of medium stiffness having modulus of elasticity E-15, E-35 and E-65 is considered. Load of 40Kn/m of dead load and live load and seismic load as per IS:1893 (Part I):2002 considering of zone V is applied on 8-story plane frame .The analysis is carried-out using Finite Element Analysis (contact surface pairing) to evaluate the interaction between Soil-pile. The results are evaluated in the form of X- Displacement, Y-Displacement, von misses stress contour, Contact Pressure and their contact status. From the results conclusion is made that soil having Young's modulus of elasticity E-35 shows greater stiffness that than E-15 and E-65.these results are shown by graphically and the contour diagrams of the respective analysis for different types of soil. At the end the future scope of the project is discussed with references.
