Old Steel Section Properties

[NWIEngineer]

Hello,

This is a continuation of a topic discussed in thread507-136556.

I am looking for the cross section dimensions of a 24CB-120 beam. According to the closed thread, it is listed in a "1946 Steel Manual".

Does anyone have the dimensions for this beam type (tf, tw, bf, d)? If so, please let me know.

Thanks.

I know that AISC has a historic shapes database that is available on their website as an excel sheet. I'm not sure how far back it goes, nor how in depth it is.

NWIEngr,
From the US Steel Pocket Companion, 24th Edition, Reprinted in 1937, I found the following:
The CB (which stands for Carnegie Beam) CB 242 with a weight of 120 pounds per foot is a 24.31" deep, 12.088" wide flange that is 0.930" thick. The web is 0.556" thick. The strong axis I=3635.3 in.4, S=299.1 in.3, r=10.15 in.

My 6th Edition of the AISC Manual of Steel Construction (1966) shows a 24 WF 120 with exactly the same dimensions & section properties.

I hope that this helps.

OldPaperMaker.....that should work. Thanks!!! I'll have to be on the lookout for some of those old manuals.

PE2012.....I had seen the AISC historical list, but you had to be a paid member to get them. Paying wasn't the problem, but paying with no assurance that what I saw would help was. Thanks anyway.

"AISC Iron and Steel Beams 1873 to 1952" - get yourself a hard copy from AISC for your library.

I believe PE2012 was referring to the free excel spreadsheet AISC provides with many historical shapes.
See the following link in case you need some other data later down the road.

You can download a (free) complete copy of "AISC Iron and Steel Beams 1873 to 1952" from this page of my website:

Just in case you are wondering... it's legal. This book was published, in 1953. The copyright was due for renewal (by AISC) twenty-eight years later (1981). AISC did not renew the copyright; therefore at the end of the twenty-eighth year the book (and all the information in it) entered the public domain - permanently. Copyright renewals for books or failure to renew is not difficult to verify. Records are maintained by the US Copyright Office. Also, both Rutgers University and Stanford University maintain searchable data bases. My work indicated that all three sources are complete and accurate.
See this Engineering FAQ where I outline how to make these checks:

For reference, "AISC Iron and Steel Beams 1873 to 1952" has been replaced by AISC "Design Guide 15". See this link:

http://www.aisc.org/DynamicQuestion.aspx?Grpid=6&QueId=1664&ste=_Preview&id=2100&type=0

For the most part, the information on beams and columns in Design Guide 15 for sections from 1952 and earlier was taken directly from the earlier book. I have used both sources... IMHO the way the information is presented in the 1953 book is superior to Design Guide 15. Of course for sections newer than 1952, Design Guide 15 is the way to go.
