Bearing Capacity of Eccentrically Loaded Circular Footing Supported on Reinforced Sand
In the recent past, investigators have given less attention on circular foundation. Thus, this research deals with the strength of circular foundation on reinforced sand. There are total 48 numbers of tests conducted on model footings of radius 10 and 5 cm and eccentricities varying from 5 to 15 mm with an increment of 5 mm. Square shaped geonet is used as reinforcing material having aperture size of 1.637 mm. There are three layers of reinforcement used, i.e., from 0 to 2, where the distance between reinforcing layer and base of foundation is 0.35D and distance between two reinforcing layers is 0.25D. The test tank has size of 0.60 m × 0.60 m × 0.30 m. This test is carried out on dense and medium dense sand. Relative density is 71% for dense sand and 51% for medium dense sand, calculated as per IS code method. Load-settlement curve of each experiment is done from which bearing capacity is calculated by tangent intersection method. The result showed that rise in reinforcing layer increases the bearing capacity, whereas rise in eccentricity has decreased bearing capacity. The results are also compared with different existing theories, with unreinforced and reinforced dense and medium dense single entities and bearing capacity ratio (BCR) which are calculated.
