Easy question - I think this is just an actual vs nominal issue

Easy question - I think this is just an actual vs nominal issue

(OP)
I'm looking at a bunch of old Atlantic Richfield Oil Co drawings, and a lot of their roof purlins are called out as W10x11.5

Is this the same beam listed in AISC as W10x12?

For my purposes, anything close to a W10x12 is way more than adequate, so I don't have any type of stress or deflection issue, I just wanted to know.

I found that site too, but there doesn't seem to be any properties of any shapes; all i found was listing what shapes they stock, but no details.

You can download shape databases from AISC here:

http://www.aisc.org/content.aspx?id=2868

In the meantime,

W = 11.5
A = 3.39
d = 9.87
bf = 3.95
tf = 0.204
tw = 0.180
Sx = 10.5
Zx = 12.2
Ix = 52.0

Slightly less than the modern W10x12

Thanks all.

Have yourselves a good day.
