RE: 1930 Steel Section Properties

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

FYI,

The text "Iron and Steel Beams 1873 to 1952" is no longer available from AISC.  Its successor is AISC Design Guide 15, which contains all of the shapes data from that text, plus the data for sections which have been discontinued from the Manual of Steel Construction since 1952, along with guidelines for the Retrofit and Rehabilitation of Steel Buildings. 

If you are interested in getting your own copy of this text, it is available for $39 (non-members) or $26 (members) at www.aisc.org > Bookstore > Design Guides

Chris,

From the Iron and Steel Beams: 1873 to 1952 (available from AISC):

B26 w/81 plf (Bethlehem steel produced around 1927 to 1930)
A=23.90 in2
d=25.78 in
b=9.47 in
tw=.44 in
m=.872 in (thickness of flange at web)
n=.495 in (thickness of flange at tip of flange)
Ix=2600.1 in4
Sx=201.7 in3
rx=10.43 in
Iy=84.3 in4
Sy=17.8 in
ry=1.88 in

For the 12x8, I did not find anything listed under the beams, but found
this under columns in the publication:

H 12/8 w/55 plf (Bethlehem steel produced around 1928 to 1930)
A=16.27 in2
d=11.875 in
b=8.12 in
tw=.43 in
m=.745 in (flange thickness at web)
n=.668 in (flange thickness at tip of flange)
Ix=406.9 in4
Sx=68.5 in3
rx=5.0 in
Iy=61.5 in4
Sy=15.2 in3
ry=1.94 in

HTH,
