Develop a spread sheet to compute allowable total vertical column loads using the ASD method
and factored ultimate vertical column loads using LRFD. The spreadsheet should consider only
vertical loads on a square or continuous footing bearing on single uniform soil. It should allow
the input of footing width, depth, water table depth, soil strength parameters, a factor of safety
for ASD, and a geotechnical resistance factor for LRFD. It should compute the bearing capacity
based on both Terzaghi’s and Vesic ́’s methods.
