Through Plate Strengthing CHS
Through Plate Strengthing CHS
(OP)
i have a truss formed out of CHS (Circular Hollow Section) where diagonal members are welded to Chord ,after checking the limits as per AISC chapter K ,found that joint require strengthening as Chord Plastification capacity is less than diagonal force .
what would be easier for fabricator is to reinforce the joint using through plate welded to both sides of chord ,however for Architectural reasons the Diagonal members should be also direct welded to the Chord . does anyone have design guides for these type of reinforced connection?

Have a mathcad worksheet for that, based I think on the attached article, will post later.

Thickening the chord ... maybe too much for just an architectural application.
It has guidelines for such design.
