Side-Loaded Wood Members

[enigma2]

I need to support a side load off of (2) 2x12s nailed together with 3 rows of 10d nails at 12" o.c. How do I calculate the maximum point load to the outside face of the built-up member to know if it's adequate or if I need to have more nails added?

Some engineers would design the additional connection for half the load. Saying the the two ply nailing will add to the strength. Others say to design the connection to transfer 2/3 the load and still use the two ply nailing to help. This is to account for critical slip of the connection between the plies. A few others have said you only need to connect for half the load. I am between the half and 2/3 the load. But it really depends on the situation.

If you are using a face mount hanger, the nails in the hanger do not count as part of this transfer connection, per most hanger manufacturers. Also you need to note that the connection is to be placed half to each side of the hanger.
