Burger Joist chord sizes

[NITTANYRAY]

I have a Burger joist catalog from the 1970s.
They have a table that lists the chord properties but the they designate their chords using an odd section number.
I was able to determine from their chart that the joist I am analyzing has a chord section number 0859 but they do not
say how this equates to the chord numbers in their load tables (ie. 14J4 or 14J5 etc.) They show a total of 21 different chord sizes in their properties table but the load/span tables only show 15 different chord sizes so I am hesitant to assign a chord number based on the location in their table of the chord that is closest to what I measured in the field.
Does anyone know what chord size a 0859 would be equivalent too?

Have you tried contacting the Steel Joist Institute?

A lot of burger joints are made with bar joists. Ha! Sorry. And sorry, I don't have any product related info for you but am just writing to say that as a last resort you can take all the specific measurements and analyze it like the truss it is. Hopefully the Steel Joist Institute can help though, as Uncle Jed Clampett wrote.
