I am currently designing a new Cafeteria/Auditorium (Cafetorium?) building for a local high school. The dining hall will double as an assembly space to view performances by the various school clubs and general student body. I've seen in both the IBC and the NFPA 101 the mention of Smoke Protecting the seating area, but I have yet to see where either of these codes requires this space to be smoke protected. Also in addition to this the NFPA 101 has different requirements for the stage and accessory space depending on how I classify the performance area. (Stage or Platform?) I would like to classify the raised performance area as a Platform so that fireproofing of the proscenium wall (2 hour) and all the walls separating the accessory spaces (1 hour) will not be needed. Is there a place in the NFPA that strictly sets the line between what the stage and platform is? All help is greatly appreciated! Thanks!

Stage defined in IBC .... if not a stage, then it is a platform...... both are defined in the code. IBC section 410.. Pay close attention to the wording of 410.3.... it states something along the line of all the following items must be included to be considered a stage ( 410.3.1 through 410.3.8), if you don't ; then you have a platform.....
Hope this helps

Ok please help
Which code is this required to be designed to otherwise it will end up looking like a duck bill platypus !!!
Smoke protected seating should not be required.
Decide if there will be a true stage with fly and everything or just a raised area for someone to stand on

you are talking about an E use group, it seem to me all the spaces are considered part to the E Group and therefore you do no have to meet the separate spaces provision except for exiting or if locally amended proscenium stages which is defined
