6-Story Braced Frame Analysis
6-Story Braced Frame Analysis
(OP)
I am doing an Seismic Analysis on a 6-Story inverted Chevron Brace system, similar, to the Sabelli Report if anyone is familiar with that? The question i have is why did they have to include a "dummy column" - non Braced Frame Column to the system. As you can see from the attachment.
If anyone has an answer, please respond as soon as you can.
Thanks,
Tim

Maybe if you posted a link to the report you would get more accurate responses.

I think you are talking about dummy column as in "zipper column" in the V bracing system. This was developed by Dr. Leon from Georgia Tech University. I attended a seminar and he said he did some studies that showed that dummy column (zipper column, thats what he called) would help in the overall strength of the system. I do not have any report to send you. But I do have his e-mail address: rleon@ce.gatech.edu
He is avery nice professor and I am sure will be able to answer your questions. Please do share back with us your findings.

I agree with SteelPE that it is likely meant to represent the "leaner" columns that contribute to the P-Delta effect on the braced frame.

Has anyone ever used this method for wind analysis?
