Six cone penetration tests and four exploratory borings have been performed at the site of a
proposed warehouse building. The underlying soils are natural sands and silty sands with occasional gravel. The CPT results and a synthesis of the borings are shown in Figure 9.17. The
 
warehouse will be supported on 3 ft deep square footings that will have ultimate LRFD design
downward loads of 100 to 600 k and serviceability loads of 100 to 480 k. The allowable total
settlement is 1.0 in and the allowable differential settlement is 0.5 in. Using ASD with these
data and reasonable factors of safety, develop design charges for vertical loads (both ultimate
and serviceability) and values of, ma
,KA, and KP for lateral design.
