Fixed End Moments for 2 x Different Point Loads

Hello all

I am trying to find or work out how to calculate the Fixed End Moment (FEM) for 2 x different point loads.

I have the following sketch:-

All of the FEM tables I have found don't have an example where there are 2 x different point loads and I was wondering if any once could shed any light on this.

Thank you

Try superposition of the two load conditions; do one load at a time and then add the two.

I guess as well as an alternative to superposition, you could resolve to a single force at the centroid of the two forces and then apply a standard tabulated case of a single point load (not central) at a given distance from the supports.

EDIT - more I think about this, not sure if correct. So definitely test it.

superposition : easiest way ("Civil engineering formulas" - Tyler Hicks - McGraw-Hill)

Listen to the old guys!

Another approach is to find the end rotations for a simple span, then calculate the two moments required to produce zero rotation at both ends.
