Notes:
1. Tabulated values are allowable superimposed loads. Purlin and all other load weights have not been subtracted from them.
2. Allowable loads have been calculated in accordance with 1996 AISI Specifications.
3. Bearing must be checked using actual bearing length and loads.
4. Wind loads can be obtained by multiplying tabulated values by 1.33.
5. Tabulated values are valid only if the compression flange of the section is adequately supported laterally.
