Foundation Load

Foundation Load

Foundation Load

How does one calculate foundation load.  Meaning "how many pounds per foot does a foundation exert on the soil.  I realize that many variables such as roof design, exterior finish and other things affect it.  Is there a software program available for calculations or a rough generic table of some kind?

RE: Foundation Load

No, you simply add up all of the loads from the weight of the structure, then add in the effects of loading ie live load and wind, then apply this to your foundation area.

This should be a simple basic technique within the grasp of every engineer and should not require the aid of software.

RE: Foundation Load

Foundation engineering does not have the same prescion as structural engineering, due to the variability of the soil properties. Therefore th foundations loads need to be reasonably accurate, but not exact. The AISC manual has tables of weights of common building materials and building systems which greatly aid the computation of the weight. However except for the simplest structures, it is still somewhat time consuming. Consider how you are supporting the loads with the foundation. If you are going to do a single mat the it doesn't matter so much. If you are going to use individual spread footings or pile caps, take careful notes on how much each componets weighs and try to break areas up into logical groups that would be supported by the foundtion
