Table is calculated using ASCE 7-05 "Minimum Design Loads for Buildings and Other Structures ".
Values cannot be utilized for buildings with a peak height greater than 40'.
Values cannot be used for buildings with a roof pitch less than 7° or greater than 270.
Fastening pattern is the distance between fasteners running parallel to the panel length.
Fastening pattern perpendicular to panel rib is 8- ole, i.e., one fastener next to each major nb,
Calculations use pullout values provided by the screw manufacturer.
Factor of safety used for pullout is 2.25 when attaching to steel and 3-00 when attaching to plywood & lx4 strips. Adjust values
accordingly for a different factor of safety.
Panel Spacing limited to L/180 deflection for loads acting towards the surface of the panel.
See Diagram below for roof zone definition.
