Reinforcement of Cold Formed Chord Joists
Reinforcement of Cold Formed Chord Joists
(OP)
Does anyone know of a method or have any experience reinforcing Bethlehem Steel H or J Series Cold Formed Chords Joists. I also am looking for a way to attach struts/angle frames to the joists. The chords are shaped like a U with wings. The total chord is about 5" wide. The top chord faces up like a regular U and the bottom chord is an inverted U. Is it possible to weld something to the wings on the chords?

Cold forming can be done with plates to significant thicknesses; If I remember correctly off the top of my head AS/NZS 4600 says up to 25mm thick.
If you have a plate thickness of 3mm or more, I would say welding is possible. That doesn't mean to say you can definately weld. You probably need to consider the application and see if the base steel strength without cold working could span with the applied loads in your application.
