706.2 Structural stability. Fire walls shall have sufficient structural stability under fire conditions to allow collapse of construction on either side without collapse of the wall for the duration of time indicated by the required fire-resistance rating.
I have heard this described as requiring the fire wall to be structurally independent, though that isn't the exact wording.
But section 706.9 allows pentrations per 713, which are basically the same as for any other fire-rated assembly. So, how do you maintain structural independence with building utilities penetrating a fire wall?
The situation I am looking at deals with a fire wall used as a horizontal exit, and the requirement to provide standpipe connection on either side of the exit. It has been suggested that the pipe supplying the standpipe cannot penetrate the fire wall because that would not meet section 706.2.
Any thoughts?
