1B
R-2
Fully sprinklered per NFPA 13
1. 2 hr U.L. design pre-cast concrete plank floor bearing on 2 hr U.L. design CMU per Table 601.
2. These masonry bearing walls are also corridor walls that still require a minimum 1/2 hour rating per Table 1018.1 so the walls are not permitted to have unprotected openings.
3. The planks are installed on +/-1/8" masonite pads for erection purposes that compress leaving no more than 1/16"
gap. Reason would say that this is a "joint" but is it one that requires anything more than filling it with mortar (as the bottom course is)?
4. This gap is not for seismic or expansion requirements. Is it the intention of the code that it must be protected any more than any other mortar joint? Any formal technical opinios on this?
Thanks for your opinions.
