How would you classify this frame?
How would you classify this frame?
(OP)
I am struggling to classify this steel frame-
Seismic Design Category D
It is existing and I am trying to justify that it works
Thanks

I was leaning toward moment frame. I may go with the R of 3 to be on the conservative side.
I agree about the hinge also
I appreciate the input

The frame is existing. I may be wrong, but I would be suprised if it meets the detailing requirements for any system in AISC 341-05. I would use the factors for Steel System Not Specifically Detailed for Seismic Resistance because they are somewhat consevative compared to other steel frame systems.
