looked through all the old AISC manuals back to the 1st edition, along
with a Cambria Steel manual from 1906. I couldn't find the 7" x 9.8# I
either. HOWEVER, I did notice that there is a standard channel shape
of 7" x 9.8#. Could the drawings be noted incorrectly? The channel
designation might be the key.
Properties: d=7", b=2.09", m=.523", n=.210", tw=0.210" (where m and n
are the thicker and thinner thicknesses of the flanges, respectively).
Hope that helped,

p.s., I double checked the dimensions listed below and they are given

Subject: Section properties of old steel beams
I'm working on a small addition to a building in San Francisco
built in 1915. There are several beams for which I need some
think flange width and thickness, overall depth and web
thickness would be
all I need. The beam designations are:
20" x 65.4# I
10" x 25.4# I
8" x 18.4# I
7" x 15.3# I
7" x 9.8# I
I'd appreciate any help you fine folks (with old steel manuals)
can give me.
Thanks in advance.
