Answer:
Explanation:
When a Net soil pressure is specified the load is compared against a modified soil capacity as shown below:
Soil Capacity = Bearing Allowable (user-entered) + Footing Self Weight + Overburden (user-entered)
If the sum of Footing Self Weight and Overburden do not equal the soil weight which was present above the footing/soil interface strata prior to excavation then the modified soil capacity provided by the program is incorrect. In this circumstance the Net Allowable Soil Bearing value should be specified as a Gross value in the program, and the magnitude of Bearing Allowable should be increased by that pre-excavation soil weight.
