cross grain bending
cross grain bending
(OP)
Does anyone know of a code reference that prohibits cross grain bending as a load transfer mechanism? I have read numerous articles that state things such as "wood is weak in cross grain bending" or "this would create cross grain bending". Is there no value for cross grain bending? I know that it is not desirable, but the loads I am working with are pretty small and I may be able to simplify the design. Any comments are appreciated.
Thanks,
Rob

"In wood diaphragms, the continuous ties shall be in addition to the diaphragm sheathing. Anchorage shall not be accomplished by use of toenails or nails subject to withdrawal, nor shall wood ledgers or framing be used in cross-grain bending or cross-grain tension."
Note this is the Earthquake loads section, so I have not found a reference in the IBC that covers non-seismic applications. Hopefully the UBC has additional guidance.
