Beam Web Allowable Stresses
Beam Web Allowable Stresses
(OP)
I am analyzing beam with knife plate welded to web and top flange using quadrilateral plate elements (see attached screen shots). The most stressed element is on beam web just below knife plate subject to both axial compression and bending stresses (fa=Sx, fby=6My/t2). Question is how to calculate beam web allowable stresses Fa and Fby? Can AISC interaction formula fa/Fa+fby/Fby<1.0 be used? As always I appreciate your help.

For practical, real world design, I think that this would be best handled using a plastic design method such as the yield line method. Given my druthers, I'd also run the stiffener full depth in this application unless there's going to be ten thousand of these things.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
