Old I-Beam Properties
Old I-Beam Properties
(OP)
I have a bridge that I'm analyzing for a heavy load. The bridge was designed back in 1926! Two different I-beams are called out. They are a 10I22.4# and a 15I42.9#. Does anyone know where I can find the dimensions and properties of these sections?

B67 - 10" deep - 22.4 #/ft
Flange width 5.5000"
Web thickness 0.252"
B7 - 15" deep - 42.9 #/ft
Flange width 5.500"
Web thickness 0.410"
My 1934 Bethlehem Steel manual has a I15 x 42.9 lbs with the same dimensions listed above. It also has the following properties:
Ix=441.8 in4
Sx=58.9 in3
rx=5.95 in
mean flange thickness 5/8"
My Bethlehem manual doesn't have a 22.9 # 10" I shape.
Are you able to measure the actual beam to verify its dimensions?

SlideRuleEra's website has the 1923 Carnegie pocket companion scanned in. I bet it has what you're looking for.
