Brace Length Reduction due to Gusset Plate (SCBF)
Brace Length Reduction due to Gusset Plate (SCBF)
(OP)
Has anyone seen any references that deal with the unbraced length of braces in special concentric braced frames. Specifically, I'm looking for some sort of reduction in the unbraced length due to the gusset plate bracing the end of the brace member, or the gusset providing some sort of fixity so I can adjust my K factor.
P.S. I'm using HSS braces.
Thanks.

That looks like some good information. I'm printing them out right now, these need to go into my files.
Thanks,

However, many braces are designed as pinned and you have to watch out that you detail the gusset to allow out-of-plane buckling to occur - See Figure 2.8 in the Steel Tips link (second link) above.
