RE: Mechanical Roofs in a Structure
For instance: If the penthouse is a small structure with a separate lateral system and it meets the IBC requirements, I probably would not consider it to be an additional story. If the penthouse is approaching the 1/3 area limit and its lateral system is a continuation of main buildings lateral system, I might consider it to be an additional story.
This really is not an ETABS specific question. The "Structural Engineering Other Technical Topics" forum has more traffic and the question would probably get more attention in that forum.
