Derivation of the AASHTO formula of interior girder moment

The interior girder moment formula for one lane loaded for the AASHTO LRFD method is: $$\begin{align} mg^{SI}_{moment}&=\left(1.75+\frac{S}{3.6}\right)\left(\frac{1}{L}\right)^{0.35}\left(\frac{1}{N_c}\right)^{0.45} \\ &=…

How is drilled shaft lateral resistance calculated using LPile?

The AASHTO LRFD Bridge Specification, Section 10.5.3.3 says "shaft lateral resistance" should be checked at the strength limit state (i.e. factored loads). How is shaft lateral resistance determined using an LPile model? Is it the lateral load…
