AISI S100 R-factor & Panel type
AISI S100 R-factor & Panel type
(OP)
Hi all!
I am checking a cold formed purlin to AISI S100-16 specification and I am having some trouble to determine if my situation is covered by the specification. On determinig R-factor, section I6.2.1 refers to "Through -Fastened to Deck or Sheating". The roof panel is an insulted panel composed of a 4" thick isulation between to steel sheets, as in image attached.

Does anyone know if this type of panel is to be considered in the scope of the specification? I'm having trouble identifying which type of sheating is being considered. If not, do you know how to approach this particular design accounting for pannel torsional restraint?
Thanks!!

I am not aware of an approach to check if the panel-to-girt connection is satisfactory to use this section of the code. Perhaps a midspan brace can be added to the compression flange (suction case), and the unbraced length would be low enough to get you girt to work. Also upping the gage would help a little, since you are only looking at the unbraced length between inflection points.
