1982 UBC standard
1982 UBC standard
(OP)
I have an interesting project in front of me... I have to verify that an existing structure, built in the early 80's, was constructed to the 1982 UBC in force at the time. Any advice on strategy?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

You might want to check for building permits, sometimes they list the Architect/Engineer who did the work, something between 82 and now might show up.
Check with the assessor also, they may show a historical jump which might indicate a significant investment (renovation). They will also show perhaps the realtor who handled the sale, that might be worth chasing - if it was sold between 82 and now.
Intervies the tenants.
Good luck

Also, the allowable stresses for solid wood members underwent a big change in 1991.
There are others.

I hope you have an experienced engineer to work with on this one; The internet is definately not going to do the trick. It is my further hope that your fees are representative of the level of difficulty you're going to face as well!
Some ideas that come to mind from what I have seen in structures around that age:
1. Manuals of tables for frames and ready-analysed structural components were very commonly used in offices before the advent of desktop computers. I still have a collection of tables and books from my Father that have been neatly eclipsed by excel... But that meant that frames were often less refined, since iterations took much longer.
2. ASD & WSD. LRFD are unlikely in a structure of this age, but this can depend on the jurisdiction. Some areas were limit states (or strength design) very early on.
3. If you don't have the drawings, your brief is impossible. You can determine if the structure was built to code, but you cannot determine if the design was to code. When was the last time you saw everything on a job match your drawings, or a project that required no site remediation work?
Wishing you the best of luck,
Hoping you'll keep us up to date,
Cheers,
