Unistrut Properties Calculation
Unistrut Properties Calculation
(OP)
I have a project in Los Angeles in which I have specified a considerable amount of unistrut. I specified the unistrut based on the published allowable values in the Unistrut catalog. LA plancheck is requiring calculations verifying the allowable properties shown in the catalog since Unistrut does not have a LARR report. Has anyone come across this issue before? It seems odd that we have to provide cumbersome AISI hand calculations to justify tables that have been used for decades without a problem. Even OSHPD and DSA are OK with the published Unistrut tables. Any thoughts would be appreciated. Thanks!

Another tack to use it to find the plan checker's supervisor. The supervisor being more senior, he/she may have a lot more history dealing with Uni-strut and might be agreeable to your argument.

I agree with Ron, if Unistrut publishes the load tables, they should be able to back up with calcs if requested. You mentioned you spoke with a Unistrut rep, was that person in the Engineering department? If not, I would recommend calling them back and ask for their Engineering department and see what that yields. Might not help, but it is worth a shot.

Unistrut "holes" also cause theorectical issues: Who is the "LA plancheck" and how do you protest his/her/its excess requirement?

I can't believe that in this economy that they are that busy that they can afford to lose customer base to competitors.

Better, more accurate values are already available. It would be equalto requiing I calculate the properties of a I beam or channel because the two webs have a slight angle to them.

I could find no code evaluation report for Unistrut.

I do believe you have above and beyond the call, Hope you get invited to the Unistrut Christmas party for doing a better job than the rep.
When in doubt, just take the next small step.

Corporate arrogance I suppose.
