Notes:

  1. Above loads include the weight of the member. This weight must be deducted to arrive at the net allowable load the beam will support.
  2. Long span beams should be supported so as to prevent rotation and twist.
  3. Allowable uniformly distributed loads are listed for various simple spans, that is, a beam on two supports. If load is concentrated at the center of the span, multiply load from the table by 0.5 and corresponding deflection by 0.8.
  4. The lateral bracing factor should be multiplied by the load to determine the load retained based on the distance between lateral braces.
