Looking for Inryco Lateral Diaphragm Data Manual 20-2

Looking for Inryco Lateral Diaphragm Data Manual 20-2

(OP)
Hi folks,
I'm working on a project that has supporting calculations which reference an Inryco Lateral Diaphragm Data Manual 20-2. The manual would be of great use in evaluating the roof deck strength and how it was evaluated when it was constructed in the 1980s. Does anyone happen to have a copy of the manual that you could share?

Also this reference to 20-2 in an Ambrose book:

Or try contacting the current "owners" of the former company to see if they have any archival information:

JAE,
Thanks for the replies!
As you suspected, the 1092 report you attached was unfortunately not what I was looking for.
I did see the reference to the Inryko report in the USC textbook and actually talked to the textbook author, who is now a long retired professor. Unfortunately he was not able to help me.
I also talked to Inland building systems, who told me that they did not have legacy documents as the company had changed hands several times.

I also checked out SlideRuleEra's website (here) but didn't see anything.

I do have a 1973 Inryco Floor deck catalog (21-1) but don't have the 20-2

A common older reference for diaphragm design is the Army Technical Manual, Seismic Design for Buildings, TM 5-809-10 (Navy NAFAC P-355, Air Force AM 88-3). Here is a link, but the quality isn't the best: https://www.nrc.gov/docs/ML0322/ML032230471.pdf. If you search, you may find a better scan. I am attaching a different scan of the chapter on diaphragms incase the linked document has problems. Also, you might try contacting the Steel Deck Institute, they may be able to help you find the Inryco manual.

@wannabeSE - Thanks for the input! Unfortunately my project is licensed using the Inryco document in it's calculations, therefore substituting a different reference document would not be a solution.
Great suggestion on contacting the SDI, I put a call into them earlier this week and they are looking.

RE: Looking for Inryco Lateral Diaphragm Data Manual 20-2

Sorry, but I only have 21-12, 21-13, and 21-19, along with 23-1.

No 20-2.

@msquared48 - Thanks for checking!

RE: Looking for Inryco Lateral Diaphragm Data Manual 20-2

Mike - perhaps send those to SlideRuleEra to get on his website?

Thanks for coming back to close out the thread and for sharing the PDF with us. Classy.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Thanks Ken!
