Robertson Deck Question QL-WKX

[cab7320]

I have a building with 1972 plans that call out robertson decking, QL-wkx /20-20 and /16-16 (in raceway span only). Its an old bank building. I am trying to find shear capacity info for the bare deck at the raceway with runs the full length of the diaphragm. We are modifying the square floor plate to be a donut with interior courtyard and need to check the shear in the diaphragm at the raceway. i have seen some other robertson deck info on this forum, but couldn't find the ql-wkx type specifically. The 1980 ICBO report posted by others is pretty good i just don't know if the ql-wkx an exact match for any of the ones in the report. Any help is appreciated.

I'm not familiar with the specific manufacturer, but do you know if they were members of the Steel Deck Institute? If so, you may be able to contact SDI and see if they have any information on record that they can share.
