When applying the 2006 IBC, Section 705.2, how does one determine the structural integrity of the wall assembly. Design Professiona has submitted a wall assembly per UL U419 giving a total wall thcikness of 6 sheets of 1/2" wallboard, RC channels and 3 5/8" metal studs to construct a 3-hour fire wall. The roof assembly continues over the fire wall but it appears the wall meets the section for compliance. This wall is to maintain the fire area less than 12,000 SF for fire area since an automatic fire protection system is not a reasonable options based on location. Is it the intent that the roof should collapse on either side of the wall without impacting the wall, or is the wall supposed to maintain any loads against it under fire load conditions. If the steel bends down on either side of the wall, the wall needs to remain standing correct. Does the UL design tak into any consideration the structural integrity or stability?
