Extracted text: Civil Engineering A strip footing is to be designed to support a dead load of 500 kN/m and an imposed load of 300 kN/m at a depth of 0.7 m in a gravelly sand. Characteristic values of the shear strength parameters are c'=0 and o'=40°. Determine the required width of the footing if a (lumped) factor of safety of 3.0 against shear failure is specified and assuming that the water table may rise to foundation level.
