Notes

  1. The beam capacities shown above include the weight of the strut beam. The beam weight mjust be subtracted from these capacitites to arrive at the net beam capacity.
  2. Allowable beam loads are based on a uniformly loaded, simply supported beam. For capacities of a beam loaded at midspan at a single point, multiply the beam capacity by 50% and deflection by 80%.
  3. The above chart shows beam capacities for strut without holes. For strut with holes, multiply by the following:
    • OS by 88%
    • OS3 by 90%
    • RS ( 9/16 holes ) by 88%
    • RS3 ( 9/16 holes ) by 88%
    • RS-MOD ( 3/4 holes ) by 85%
    • RS-MOD2 ( 9/16 holes ) by 88%
    • KO by 82%
