Parametric Study on Performance of Conical Shell Foundation Using FEM Modeling
A Shell foundation has been considered the best shallow foundation for transferring heavy load to weak soils because of the high bearing capacity values, whereas a conventional shallow foundation submits to excessive settlement. In this paper, two parametric studies were carried out on conical shell foundations using FEM software ANSYS to study the effect of the rise to radius (f/r ratio) and thickness on the strength and settlement of conical shell foundations. In the first study, various f/r ratios chosen were 0.5, 0.75, and 1. The results indicated better performances for the conical shell foundation with an f/r ratio of 1, due to its increased membrane stresses and the contact area between the shell and soil. The shell thickness was varied in the second study from 40 to 80 mm, and the results showed that as the thickness increases, the settlement reduces. The ultimate load increases up to a thickness of 70 mm, which is due to the increase in the rigidity of the foundation. From the parametric study, it was understood that f/r ratio and thickness are two main parameters that influence the behavior of shell foundations.
