The potential benefits of fiber reinforced soil foundations over unreinforced sands subjected to inclined loads are investigated using total of 93 small scale model footing load tests. The effect of soil reinforcement (percentage of fibers), effect of thickness of reinforced layer, effect of soil density and effect of load inclination on some prominent parameters such as ultimate bearing capacity, vertical settlement and horizontal deformation are investigated in this study. Test results indicate that the use of fiber reinforced sand brings considerable improvement in ultimate bearing capacity, vertical settlement and horizontal deformation of foundation. A statistical model using multiple linear regression analysis based on present experimental data for predicting the settlement (Sp) of square footing on reinforced sand at any load applied was done where the dependent variable was predicted settlement (Sp).
