old steel section properties
old steel section properties
(OP)
Does anyone have information on old/obsolete steel sections? More specifically, I need section properties for beams from around 1930, called out similar to either "24C-76#" or "24CB @ 76#". These sections are not channels as the "C" might suggest. They look similar to wide flange sections.
Thanks,
Jason

I'd suggest you go buy it - very good publication. Go here

Your comment will be helpful.
RE: old steel section properties
Section properties are:
Depth(in), 24
Weight per foot (lb), 74.2
Area (in2), 21.70
Flange width (in), 9.000
Thickness of web (in), 0.476
I1 (in4), 1950.1
r1 (in), 9.48
S1 (in3), 162.5
I2 (in4), 61.2
r2 (in), 1.68
S2 (in3), 13.6

So I wouldn't count on it being composite.

I'm basing this on the AISC guide mentioned above. Definitely an excellent purchase.
RE: old steel section properties
I have an AISC manual dated 1946, it includes the following: WF shapes 24X9
W = 76 lb/ft, A = 22.37 in^2, d = 23.91 in, bf = 8.985 in,
tf = 0.682 in, tw = 0.440 in,
X-X axis I = 2096.4 in^4, S = 175.4 in^3, r = 9.68 in
Y-Y axis I = 76.5 in^3, S = 17.0 in^3, r = 1.85 in
detailing dim
d = 23 7/8 in bf = 9 in tf = 11/16 in
tw = 7/16 in tw/2 = 1/4 in
a = 4 1/4 in T = 21 3/8 in k = 1 1/4 in m = 25 5/8 in g1 = 2 1/2 in c = 5 /16 in g = 5 1/2 in
this is a little newer than you say your structure is, but the beam depth and weight match.
I also have a Carnegie Steel Pocket Companion (1923), it lists the exact beam that dbuzz mentioned.
maybe this will help.

Would someone be able to tell me if these weights match up to the CB series in the AISC steel design guide #15 or any other series for that matter?
