Allowable uniform loads are based upon 3 equal span lengths.2. Negative wind is wind suction or uplift and is NOT increased by 33 1/3%.3. Live Load is the allowable live or snow load.4. L/180 deflection is the allowable load that limits the deflection to 1/180 of the span while under positive orlive load.5. The weight of the panel has NOT been deducted from the allowable loads.6. Negative wind and live loads are limited to combined shear and bending using Eq. C3.3.1-1 of theAISI specification.7. Live Load values are limited by web crippling using a bearing length of 2”.8. Web crippling values are determined using a ration of the uniform load actually supported by the topflanges of the section.* Oil canning is a natural occurrence in metal panels and is not a cause for panel rejection.MAX-RIB
