Notes:
1) The allowable design stress Fb is based on the basic design stress for flexural members and the allowable bending stress in webs determined in accordance with the provisions of the AISI specifications.
2) Thickness and area shown are those of bare steel exclusive of the galvanized coating. Weights listed for purlins are based on the weight of the galvanized steel.
3) The allowable moment and shera were computed using a factor of 1.67 and 1.60 respectively.
4) The moment of inertia (Ix) is the effective moment of inertia and must be used only for computing deflections. It shall be used for computing allowable flexional.
