Forces Used in Analysis

The total moment used in the design of the spread footing is:

\begin{matrix} M_{u m a j} = M_{u m a j C o l u m n} + M_{m a j C G} + M_{m a j S h e a r} \\ M_{u \min} = M_{u \min C o l u m n} + M_{\min C G} + M_{\min S h e a r} \end{matrix}

Equation 4-10

The total axial load used in the design of the spread footing is:

P_{uDesign} = (\begin{matrix} P_{uColumn} + Footing SelfWeight + \\ Column SelfWeight + Uniform Surcharge \end{matrix})

Equation 4-11

Note: Spread footings are designed by first transferring all forces and moments to the center of the supported column.
