unusual building geometry and shear wall/moment frame
unusual building geometry and shear wall/moment frame
(OP)
I've been asked to look at a design for a residential wood framed building that is configured in a U shape with straight legs on approximately a 12.5d angle out from center. Middle section between the legs is approx 18' long with legs at about 24' long. middle section has a 16' opening for doors and current design calls for a moment frame tied to concrete piers. I'm familiar with typical diaphragm and shear wall design but I'm not sure about how to proceed with this configuration. Is there a design reference that can help take the geometry into account? I'm figuring I'll work around the building but I thought having an interior wall changes the approach.
Any help would be appreciated.

RE: unusual building geometry and shear wall/moment frame
The building sounds much too small to have a moment frame in it. To small for expansion joints too which I might encourage in a larger building. I've sketched out a rough concept below for your consideration.
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.
