Abstract
A structural foundation transmits all the loads from the super structure to the soil underneath safely. Due to earthquake or wind loading, the line of action of total load from the superstructure does not pass through the center of gravity of the footing resulting in eccentric loading. The compensation for reduction of the bearing capacity by increasing the size of footing is uneconomical. Geosynthetics can be used to improve the bearing capacity of the footing. In the present study a series of tests were conducted and comparative study is made when Geotextile (Fibertex G-100) is used as planar reinforcement to improve the bearing capacity of sand. Also the improvement of bearing capacity in accordance to eccentricity was studied. The test results indicate that there is significant improvement in the bearing capacity and reduction in the settlement by providing planar reinforcement until the eccentricity is 0.1 times the width of footing.
