Calculating reactions at supports if one support is elevated

  • #1

Main Question or Discussion Point

Hi guys!

How can one calculate your reactions at both ends of a simply supported beam if one reaction is higher than the other one?
Example: Support A (one end of the beam) is 100mm higher than Support B (other end) and there is a 22kN/m UDL distributed along the length of 2.5m
Does your reactions at the supports still act perpendicular or at an angle due to the elevation change of support A?

Make sure all the forces add to zero, and all the moments add to zero. With that you should be able to confirm any possible answers.

Also make sure rollers supports aren't providing any component of their reaction force parallel to their direction of free motion.
