Abstract

The earth provides all the support to any structure depending on various soil conditions. Foundations are the substructures that transmit the load of the structure to earth in such a way that the soil does not get over stressed and do not deform. Types of footings used vary depending on the type of structure, for example, in structures such as transmission towers or water tower, the circular footing is used essentially. Circular footings have been used since ages, but ring footing got less attention than a circular one, despite its greater efficiency and cost-saving nature. Thus, in order to develop new and economical technologies, studying the benefits of rings over circular footing is essential, which is the prime objective of this paper. The parameter (bearing capacity) has been studied experimentally as well as an attempt of numerical analysis is done, in order to understand the behaviour of the sand under the ring footing. The experimental values of the bearing capacity of the ring footing are obtained by performing a series of laboratory tests on the model footing for three different radii ratio 0.2, 0.4, 0.6. While numerical analysis was performed using an empirical equation available in literature. The values of these analyses were then compared and it was determined that the theoretical values were quite higher than that of the experimental values of bearing capacity.
