Historic Bar Joist Identity
Historic Bar Joist Identity
(OP)
I have come across a historic bar joist product on a project and am having trouble tracking down anything like it in the Steel Joist Institute catalog.
The joist is 16" deep. The top chord is 1. 1/2" angles, spaced by a 1/2" round web. The web is a continuous, albeit bent, member.
The bottom chord is also a pair of 1/2" rounds, welded on either side of this serpentine web configuration.
Per my limited research, the original bar joists had top AND bottom chord rounds. I can't find any reference to a system with only rounds on the bottom chord.
Any pointing in the right direction would be appreciated.
A photo of the system is attached.
