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 âbrittle finishesâ in exterior walls and interior partitions. Furthermore, footnote âfâ 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.
If you want a definitive answer, you'll need to ask one. My calculations show that a 1000 lb load hanging at the center of a 20 foot beam with the beam simply supported at each end will deflect (sag) 0.25 inches. The calculation is linear so for each additional 1000 lbs the beam will deflect an additional .25 inches.
