*Assume weight of reinforcing steel
included in unit weight of concrete.
*Assume compacted backfill
weighs the same as in-situ soil.
Assume this foundation is being designed for a warehouse that had a thorough preliminary soil
exploration. Using the general bearing capacity equation:
a. Calculate the gross applied bearing pressure, the gross ultimate bearing pressure, and
determine if the foundation system is safe using a gross bearing capacity ASD
approach. Please include the weight of the foundation, the weight of the backfill soil,
and the effect of the uplift pressure caused by the presence of the water table in your
bearing capacity…
