13" 52.5# Car Builders Channel - Dimensions Quest

[nickseman]

Hello:
I am looking for the dimensions of an old steel shape commonly used during the early part of the 20th century, the 13" 52.5# Car Builders Channel. I have looked in the Bethlehem and Carnegie books, but the furthest back I have date in the thirties and do not list this size. I suspect its use did not continue after about 1920. I especially need the web thickness, but could use all of the general dimensions if anyone has them. Thank you in advance.

In my Cambria book, I have 13x50 and 13x55, but no 52.5. t_w for the 50 is 0.79" and for the 55 is 0.94", for what it's worth.

Before this thread drops to the second page, I couldn't find anything in my material...

From other info I have it appears that a tw of 15/16 would be correct. Thanks for looking into this - I am actually surprised that I can not find the info anywhere as it appears that it was a fairly heavily used size at one time.

I looked in a 1909 Carnegie Manual, 13x50 was the maximum size, tw = 51/64"; 1926 American Bridge Manual lists 13x50 with tw = .79"

Try SlideRuleEra's site. He has a zip file for a 1923 Carnegie Manual

and an 1892 Pencoyd

Monday when I'm back in the office I'll look through the AISC CD with its zillions of shapes.

Nick,

I'm sorry but I can't find that shape. It's not in the AISC historic database. I also looked in several steel manuals from early 20th Century with no luck.
