  Information  
  Rain Load (R) is ignored  
  Monoslope, 0 slope, canopies only  
  Load Combo 6a reserved as TX canopy engineers not considering roof maintenance during wind/snow design event  
  For post unity, combined bending and axial for lateral wind and vertical D,W,S and separate check for D,Lr axial without lateral wind as roof TX canopy engineers not considering roof maintenance during wind/snow design event  
  Assuming 15 psf soil adhesion for drained clayey soils for footing uplift calculations, however drained soils can result in 0 psf soil adhesion
