Existing Bar Joist
(OP)
Was wondering what this joist likely is.
25 year old building.
Ground Snow 25 psf
Centeral N.J.
26" Deep
40' Span
6'-3" o.c. spacing typ.
bottom chord - 1 3/4 x 1 3/4 x 3/16
web rods 7/8" diameter
That's all the info. I have at this time.
Thanks in Advance!

But in order to verify model this in a 3d analsyis program to confirm the capacity of the suggested joist size.

I did reach out to steel joist and submitted online. They got back to me in 20 minutes. They felt it was likely a 26K10 joist with the information I provided. I was thinking it was a 26K6 or 7.
Trying to find a source for common bar joists and their component sizes. Do the 60, 70 year joist catalog's provide this information or is their a better resource?
RE: Existing Bar Joist
I think the practice for the manufacturers is that they use whatever components (angles, bar, etc.) they can get to provide stated capacities. So it's impossible to specifically define these.

We just ran into a similar issue and found that SJI was able to provide typical components for suspected joist sizes.
The 60 year joist catalog will provide if they were around 25 years ago.
