Angled Diaphragm Chord/Collector/Shearwall Analysis
Angled Diaphragm Chord/Collector/Shearwall Analysis
(OP)
Hello All,
I'm designing an indoor mezzanine w/ pretty light seismic loads in SDC B. I'm curious how people analyze diaphragms where the shearwalls are angled w/ respect to the chords. I know that ASCE references it as an irregularity but I've never seen an explanation of the actual physics behind how the diaphragm itself works, and how you account for the jogs in your chords. I've attached a markup of the framing plan for reference.
Thanks,
ZRC

HELP! I'd like your help with a thread that I was forced to move to the business issues section where it will surely be seen by next to nobody that matters to me: http://www.eng-tips.com/viewthread.cfm?qid=456235

Thanks for responding. It is 3/4" plywood over TJI's with wood shearwalls on all sides. It's being built inside of a pre engineered metal building so all we are really dealing with is Seismic in a low seismic zone.

Thanks so much for taking the time to mark up those examples. It helps a lot to discuss and find some outside opinions.
I need to go through those longer pdfs over the weekend to get a better feel for it but I have a much better idea of the mechanics now.
