Uniformly distributed loads
  • Uniformly distributed loads are a load that is spread across a region of the beam.
  • Best example of this is the weight of the beam itself
  • It is measured in N/m and is represented by many arrows or a bumpy line.
  • When calculating moments with the UDL, treat it as a point load in the middle of the region with the sum of the entire load.
    • e.g. For a 10m long beam with a UDL of 5kN/m, it can be counted as a 50kN point load 5m from the ends.
  • In shear force and bending diagrams, it looks like the following:
