Positive Wind is wind pressure and is NOT increased by 33 113 % 3. Negative Wind is wind suction or uplift and is NOT increased by 33 113%- 4. Live is the allowable live or snow load. 5. Deflection (U180) is the allowable load that limits the panel's deflection to U180 while under positive or live load. 6. Deflection (1-1240) is the allowable load that limits the panel's deflection to L240 while under positive or live load. 7. The weight of the panel has NOT been deducted from the allowable loads. 8 Positive Wind, Negative Wind, and Live Load values are limited to combined shear & bending using Eq. C3.3 1-1 of the AISI Specification 9 Positive Wind and Live Load values are limited by web crippling using a bearing length of 2". 10 Web crippling values are determined using a ratio of the uniform load actually supported by the top Ranges of the section SHREVEPORT.
