NOTES:

  1. The load combination for this table is roof live load plus roof panel dead load.
  2. The properties and load tables are for the panel alone.
    The panel profile has been assumed to remain constant under loading.
    The capacity of the clips and fasteners is not considered.
  3. The panel section properties have been calculated in accordance with the
    1986 AISI Specification, with 1989 Addendum.
  4. Values for 3 span condition also consider the effects of 4 or more spans.
  5. Pattern loading has been considered for multiple span conditions.
