Self-Weight and Surcharge

\begin{matrix} SelfWeight = (l_{1} + l_{2}) (w_{1} + w_{2}) \times Thickness \times δ_{c 1} \times DLF \\ UniformSurcharge = (l_{1} + l_{2}) (w_{1} + w_{2}) \times (\begin{matrix} DeadSurcharge \times DLF + \\ LiveSurcharge \times LLF \end{matrix}) \end{matrix}

Equation 4-5

Note: Except for footings in uplift, footing self-weight and surcharge are not calculated for concrete load combinations as the load is completely balanced by the soil when calculating moments and shears on the footing.
