Would Gusset Improve Deflection?
Would Gusset Improve Deflection?
(OP)
I have a 14' span over a storefront door.
The structural header is CFS.
The brick angle, which is L7x4x3/8, works for strength, but the deflection is L/366.
Would a Gusset PL 5/16 x 3 x 6 at 24" oc (or sim) improve the deflection result to attempt to satisfy the L/600?
Thank you all!

I thought about stitch welding a continuous PL 3/8 x 2 (or more) to top of vertical leg to make an L9 or L10.
Any other suggestions?
I wonder why an L8x4 doesn't come thinner than 7/16 for such a situation.
Thank you!

This is new construction rather than existing, right? And the angle is not welded to the CFS header?
I've seen engineers make a stiff long span brick lintel by welding a bottom bearing plate onto a small channel. That requires sufficient cavity space of course. And an architect willing to sacrifice it.
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.

FYI, I TEK screw all my veneer angles, at 12" oc, to CFS headers for added stability. Welding to CFS header is also a consideration for the future.
Thank you all for your ideas!
