Abstract

Ring foundations are often adopted for large and tall structures to resist lateral loads and to increase the stability against overturning. They have been used worldwide under various structures, including telecommunication towers, liquid storage tanks, bridges and offshore structures. The performance of a structure mostly depends on the performance of foundation. However, the behaviour of these foundations has not been well understood. Since it is a very important part, it should be designed properly. This paper presents the behaviour of ring footing under eccentric loading on geogrid reinforced sand of medium density. The model tests have been conducted using ring footing with ring radii ratio (Di/Do) = 0.2, 0.4, and 0.6 for varying eccentricity ratio. Parametric studies have been made to find the impact of eccentricity ratio, ring radii ratio and geogrid reinforcement on bearing capacity of the foundation.
