ASCE 7 denotes height restrictions for numerous systems. For instance, a 35ft max height is noted for Ordinary Steel Concentric Braced Frames located in seismic design category D.

How were those heights developed?

Thanks for any insight!
 
From my limited knowledge, what I understand is that height limits specified in ASCE code are largely based on post earthquake observation of the performance of similar structures rather than any specialized testing of different SFRS.
I recommend you to read this article by structure magazine to improve your perception on the height limits imposed by ASCE.
 

The following para. is copy and paste from ASCE 7

C12.2.1 Selection and Limitations
