screwed roof deck
hi to all. i have been away from the forum for a while.
at any rate, i was wondering and i already began search on data to support diaphragm values for screwing wood sheathing into light gauge metal trusses with tek screws. i already contacted eh apa and they stated that they do not have any data. however, they have some notes regarding the process that they will e-mail to me.
anyone in here who has such data, please share it.
thanks,
regards,
lutfi
