In California seismic design, what is the minimum nail penetration required for wall sheathing attachment when using 8d common nails?
Correct Answer
A) 1.25 inches into framing member
CRC Section R602.3.4 and Table R602.3(1) specify that 8d common nails used for wall sheathing must penetrate a minimum of 1.25 inches into the framing member. This California requirement ensures adequate shear transfer for seismic resistance and is critical for the performance of the lateral force-resisting system.
Why This Is the Correct Answer
CRC Section R602.3.4 and Table R602.3(1) specify that 8d common nails used for wall sheathing must penetrate a minimum of 1.25 inches into the framing member. This depth ensures adequate shear transfer between sheathing and framing, which is critical for the lateral force-resisting system in seismic zones.
Why the Other Options Are Wrong
Option B: 2 inches into framing member
2 inches of penetration exceeds what the code requires and is not the specified minimum. While more penetration is not harmful structurally, this answer reflects confusion with larger nail sizes or different fastener requirements.
Option C: 1 inch into framing member
1 inch of penetration is insufficient for 8d common nails in sheathing applications. This depth does not provide the shear capacity required by the CRC to transfer lateral seismic forces effectively.
Option D: 1.5 inches into framing member
1.5 inches is a plausible distractor but does not match the CRC-specified minimum of 1.25 inches for 8d common nails. Confusing this with the 10d nail requirement or a different code table is a common error.
Memory Technique
For 8d nails, remember '1.25 = 8d minimum.' The '8' in 8d can remind you that the penetration is less than 1.5 inches — just 1.25 inches into the framing.
