RE: Old Steel Shapes - Section Properties

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I looked more closely at my old "as-built" drawings. The 7" x 9.8# member is
a channel.  Thanks for the help.

Victor, John,

 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

	Here is the info I have on the American Standard Beams.  The
flanges are
	tapered with the thicker part (tb1) at the beam web.  I couldn't
find the
	last beam.

	Hope this helps.

	20" x 65.4# I : d = 20, b=6.25, tb1= 1.029, tb2=.55, tw=.5

	10" x 25.4# I : d=10, b=4.66, tb1=.673, tb2=.31, tw=.31

	8" x 18.4# I: d=8, b=4.0, tb1=.581, tb2=.27, tw=.27

	7" x 15.3# I: d=7, b=3.66, tb1=.534, tb2=.25, tw=.25

	7" x 9.8# I:  ???

	I'm working on a small addition to a building in San Francisco
that was
	built in 1915.  There are several beams for which I need some
dimensions.  I
	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.
