Finite Element Analysis of Vane-Shaped Footing of Varying Projection Depth under Eccentric and Inclined Loading Using Ansys Software: A Review

Abstract

When a load applies to soil strata, the soil tends to move vertically and horizontally, which causes the foundation to settle. Additionally, when an eccentric load is applied to the footing, it causes the footing to tilt. To solve this problem, an angle-shaped footing is introduced to reduce the tilt and bring it down to zero. In angle-shaped footing, either a vertical or inclined projection provided at the edge of the footing remains embedded in the soil. This projection is provided in a vane-shaped footing at the center and in both directions. The vertical downward projection at the center helps improve the bearing capacity of soil against the application of loading and also provides resistance against both overturning and sliding. Hence, the present work has applied eccentric and inclined loading to the vane-shaped footing model. The load combination until tilt in footing within the permissible limit as per the Indian Standard Code is determined. The normal stress and shear stress is also checked in horizontal and vertical directions for the same load combination at the same Vane-shaped footing model. The whole analysis was performed on ANSYS version 18.2.
