Gypsum Board/Drywall, Brittle Finish?
Gypsum Board/Drywall, Brittle Finish?
(OP)
Table 1604.3 in the IBC has a deflection limit for "brittle" finishes of L/240, and L/120 for "flexible" finishes. (This is with regard to an interior partition wall). "Brittle" and "flexible" don't seem to be defined anywhere. Is there somewhere I'm not looking that defines these terms?
I've always considered gypsum board and drywall a brittle finish for deflection purposes. Am I being too conservative?

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.

For drywall assemblies it is desirable to limit deflection to L/240 and to never exceed L/120.
