  1. A flat site is being considered for a new school that will have a steel frame and brick façade. The steel columns will have a maximum load of 250 kips, and the planned column support will consist of a 6 foot by 6 foot square footing placed 2 feet below the ground surface (to the bottom of the footing). Subsurface conditions consist of a 15-foot-thick layer of uniform silty sand (unit weight = 122 pcf, soil modulus = 160,000 psf) over stiff clay (unit weight = 118 pcf, soil modulus = 230,000 psf). Groundwater is deep. Calculate the immediate (elastic) settlement.

Repeat problem 8.2 using Schmertmann’s method, compute the settlement of this footing att = 50 years. (divide the soil into 6 layers, 3 ft thickness for each layer) 8.2) A 250-k column load is to be supported on a 9 ft square footing embedded 2 ft below the ground surface. The underlying soil is a silty sand with an average N60 of 32 and a unit weight of 129 lb/ft3. The groundwater table is at a depth of 35 ft....
