Sample Calculations
Calculation Formula Example
Wind load (sizing girts)
Wind load (lbs/sq ft) x .75 x girt spacing (ft) x wind coefficient (typically 1.1) = Allowable load/linear foot of girt

 

20 psf x .75 x 5 Ft x 1.1 = 82.5 plf

 
Live (snow) Load
(load on purlin)
Snow load (lbs/sq ft) x purlin spacing (ft) = allowable load/linear foot of purlin 20 psf x 5 ft = 100 plf
Note: These sample calculations are basic. Many different variables can affect loading. For example, drift loading, building height, geographic location, etc. Please contact Flexospan if special conditions exist.
