Pressure blocking: allowed or not?
Code Neophyte said:You're correct. A preceding section, R802.3, addressed rafter connection at ridge, hips, valleys.
Bootleg said:I have approved pressure blocking if correctly applied instead of a hanger for floor and ceiling joist.
I understand and agree. An engineering study would be in order.Code Neophyte said:IF....I understand the concept correctly (so the floor or ceiling joists are side nailed into the end of a 1-1/2" block?), then I think it does not meet the prescriptive requirement of R802.6, and could not be accepted without engineering. From a practical standpoint, however, I can't see how it is much different than the 2x2 ledger strip that's allowed by code to be used to provide bearing. Both depend heavily on only a mechanical nail connection and no direct bearing loadpath.
You would require an engineer to approve pressure blocking in SFR framing?Jobsaver said:I understand and agree. An engineering study would be in order.
