Quick question. per 2001 cbc 302.2, "Where the occupancy separation is horizontal, structural members supporting the separation shall be protected by equivalent fire-resistive construction." but does this require the openings to be protected?
I'll buy the argument that, say for doors, rated frames and installation can be required (to protect the wall), but the door itself need not be rated.
I've searched through the forums but couldn't find any code or interpretation citing. I've looked through the 97 ubc handbook, and the applications manual, and again couldn't find supporting information. so am i wrong? if not, do any of you have any supporting interpretations or such? appreciate the help.
