The Ultimate Bearing Capacity of Ring Footing with Inclined Base

The ring footings are usually adopted as a foundation for a structure having circular geometry. Generally, the bearing capacity of ring footing is evaluated either experimentally or numerically for different radii ratios. The radii ratio (ri/ro) of the ring footing is defined as the ratio of inner radius (ri) to its outer radius (ro). The bearing capacity of the ring footing having flat base is found to be optimum for radii ratio from 0.25 to 0.35. However, the effect of inclined base on the bearing capacity of the ring footing is not examined. In this study, the effect of inclined base on the bearing capacity of the ring footing is evaluated using finite element (FE) analysis. The vertical bearing capacity of the ring footing with varying base inclination (≤0, 5, 10, 15°) and different radii ratio (ri/ro = 0 to 0.75) is evaluated. The bearing capacity ratio (BCR), defined as ratio of ultimate bearing capacity of ring footing with inclined base to the flat base, corresponding to different radii ratio and varying soil friction angles is evaluated. Based on the FE results and comparison made in the study, future direction is drawn on evaluation of bearing capacity of ring footing.
