To All,
 
I guess I could research this myself, but probably getting lazy. I specified an HSS 5"x5"x1/4" stub column sticking out of the top of a concrete column to carry a light framed canopy load. The DSA plan check engineer, (California school), says that it is "not seismically compact." Where do I find out what sections are and are not comact, (AISC 13th edition?)?
 
Thanks in advance,
 
Larry Hauer, S.E.
