Channel "10 U 15" Properties. Building built in 1901!
Channel "10 U 15" Properties. Building built in 1901!
(OP)
If anyone can help, I am looking for properties of a specific channel. The drawings I am working with are from 1901. Yes 1901. An extremely long time ago. Drawings are in great shape nonetheless. Anyway, the drawings denote a built-up column made using (2) channels laced together and they are denoted as being "10 U 15" where the "U" seems obvious for a channel designation. I am specifically looking for area, moment of inertial, and x any y centroidal axis locations. Thanks to anyone that can help.

A = 4.47
Ixx = 66.9
Iyy = 2.3 (x = .64")
2.6" flange width, .436" average thickness
.24" web thickness
I doubt that this is the one you want, but it's a start.

SlideRuleEra has some later versions.

From my 1909 Carnegie, hard copy a single lattice column made up of 2 - 10C15 (12" wide) has the following properties:
A = 8.92 in^6
I 1-1 about the strong axis of the channels 134 in^4, r= 3.87
I 2-2 123 in^4, r=3.72
weight per foot 37.8
flange width = 2.6"; flange thicknesses = 0.24" & 0.633, web thickness 0.24"
Back then the books didn't list all of the info you asked for; the AISC historic manual doesn't list channels.

That certainly sounds like a match, but how did they make a "lattice column" up? Sounds like an outside channel riveted with straight plates to a second channel?

I looked in an 1893 & 1903 Carnegie Manual (PDF's). The 1893 doesn't have any latticed column tables using two channels; the 1903 doesn't have latticed columns with 10' channels.
Take at look at the Pencoyd Iron Works (1892)manual - download from SRE's site. They have several tables on steel and iron latticed columns. He also has the AISC historic shapes manual 1873-1952; that's where the attachment came from.
