Allowable loads and deflections: U - Uniform load (lb./ft.), C - Concentrated load (lb.), Cs - Allowable concentrated load per foot of length at mid-width (lb./ft.), D - Deflection (in.). Spans to the left of heavy line produce a deflection of 1/4" or less under a uniform load of 100 lbs. per square foot.

In the elastic range, deflection is proportional to the applied load for both uniform and concentrated loads. This relationship can be used to determine the deflection that any load which is less than the allowable load will produce.
