Off-diagonal bracing systems
Off-diagonal bracing systems
(OP)
Hi everybody,
I would like to know if off-diagonal (aka off-center) bracing systems are allowed in Special Concentrically Braces Frames (SCBF) according to Seismic Provisions of AISC 341-10.
Indeed I haven't found any reference to such type of bracings in the code.
Any clarification or reference about how to analyze them would be appreciated.

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.
RE: Off-diagonal bracing systems
Please find attached a sketch of what I call "off-diagonal" bracings. They are typically used when trying to avoid openings.
I guess they are not eccentrical, but rather an specific case of concentrical.
In case they are not allowed for SCBF or any other, any suggestion of how could these situations be solved?
