ibc deflection limits steel beam
with deflection limits for wood studs backing brick veneer. Code provisions and research are examined to determine if these limits are appropriate. Codes and Research What is the maximum deflection limit of wood studs that back-up brick veneer? International Building Code (IBC) Table 1604.3 gives a limit of L/240 for âbrittle finishesâ in exterior walls and interior partitions. Furthermore, footnote âfâ states the wind load is permitted to be taken as 0.70 of the components & cladding (C&C) wind load for the purpose of determining deflection limits.
