dimensioned lumber as diaphragms
(OP)
Can anyone supply me with good sound information on using dimensioned lumber as diaphragms. I had some information years back but I cannot seem to relocate it. I have many documents on plywood as diaphragms but I need to see the possibility of using dimensioned lumber.
I have been intrigued over the discussion on STAAD.]
I have it. I use it but I don't trust it and i adhor REI and their arrogance.

The UBC also allows dimensional lumber to be used as a diaphragm if "calculated by principles of mechanics" This leaves the door open for some engineering creativity.
Good Luck
