RE: Old Steel Designations

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Gina,  us old guys always carry around AISC manuals from 1926 and the like
(we never throw anything away, much to the disgust of our mates...) but you
can take the easy route and get a copy of AISC's Historical Record
Dimensions and Properties Rolled Shapes Steel and Wrought Iron Beams and
Columns As Rolled in U.S.A. Period 1873 to 1952 with Sources as Noted,
Compiled and Edited by Herbert W. Ferris  It's a slim volume, all
hand-lettered and a god-send to those who work on existing buildings.

6B8.5:  this is a junior beam, area = 2.5 in2, depth is 5.83", flange width
is 3.94", web thickness is 0.17"  Ix = 14.8 in4, Sx = 5.07 in3, r = 2.43"

8WF17:  there are a number of 17 lb. 8WF, with slightly varying properties.
Here's one:
8WFB8 8 x 5-1/4: area = 5.0 in2, depth = 8", flange width = 5.25", web
thickness = 0.23"  Ix = 56.4 in4, Sx = 14.1 in3, r = 3.36"

I suggest you get the book and double check my numbers.
