| Abstract | ||
| This study investigates the behavior of a rectangular footing subjected to inclined and eccentric load on geo-grid reinforced sand by using laboratory modeling. Small model was used to simulate the behavior of rectangular surface footings (length to width ratios of the footings were equal to 1, 1.25, and 1.5). The effect of the eccentricity and inclination of applied load on the bearing capacity, settlement, horizontal displacement and tilt were investigated. The load eccentricity varies from (0, 0.05B, 0.1B to 0.15B) and the load inclination varies from (00, 50, 100, 150) . The dry sand is reinforced by multiple layers (1, 2, 3, 4 and 5) of Geo-grid. The results illustrated that by increasing the number of reinforcement layers, the bearing capacity increased, but there is an optimum value (5). In general, for central, inclination and eccentricity loading the results indicated that by increasing the number of reinforcement layers (N) the bearing capacity increased while settlement, horizontal displacement and tilt decreased. | ||
