I was curious what the difference is between a corridor and an exit passageway. The 2012 IBC definitions say a corridor is an exit access while an exit passageway is an exit. But the definitions don't define the difference is between an exit and an exit access. Where does the exit access end and exit begin? I am an engineer and always let the architect worry about means of egress. but, I would like to have a better understanding
The reason I ask is because the live loads for corridors other than the first floor changed in 2012. Except for the first floor, the corridor live load is the same as the occupancy served (except where indicated otherwise). So a corridor for theater (assembly area) or stadium with fixed seating require a 60psf live load. While corridors serving heavy manufacturing or storage warehouses require 250psf. And, all exits require 100 psf.
