Prepare a spreadsheet to compute settlement of square footings using the e@log@p method. Thespreadsheet should allow input of: footing width, footing depth, groundwater depth, columnservice load, footing rigidity factor and Cr/(1 + e0), Cr/(1 + e0), sm′, and g as function ofdepth. Check your spreadsheet using a hand solution
For sitework computation: If a footing labeled as F-5 (occurring 3 times on the foundation plan) is described by the following sets of information: For the footing: 3.0m x 3.0m x 0.5m with a total depth of embedment of 3m relative to the NGL. For the column (attached to the footing): 0.5m x 0.5m x 5m. Working space of 1 ft is recommended along the perimeter of the footing base. Side slope considered is for every 2V:1H is observed.

Redo Problem 16.13 with the following data: gross allowable load = 184,000 lb, = 121 lb/ft3, c = 0, =26, Df = 6.5 ft., and required factor of safety = 2.5. 16.13 A square footing (B B) must carry a gross allowable load of 1160 kN. The base of the footing is to be located at a depth of 2 m below the ground surface. If the required factor of safety is 4.5, determine the size of the footing. Use Terzaghis bearing capacity factors and assume general shear failure of soil. Given: = 17 kN/m3, c = 48 kN/m2, =31.
