a A single-column highway bridge bent is to be supported on a square spread footing founded on sand. The bottom of this footing will be 1.8 m below the adjacent ground surface. The factored vertical compressive design load, P. plus the factored weight of the foundation is 4.500 KN when computed using the AASHTO load factors. The soil has e' = 0 and 6 = 31° (based on empirical correlations with SPT data) and y = 17.5 kN/m". The groundwater table is at a great depth. Using the LRFD method, determine the required footing width, B, to satisfy bearing capacity requirements.
