<br /> Assumptions:1. Load is applied to the center of footing. 2. No uplift or moment(bending)loads are applied. 3. Soil over the
<br /> footing is the only surcharge load applied. 4. Design based on 1999 ACI Code.5. All rebar is properly spaced and not epoxy- www.constructioocelacom
<br /> coated
