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.

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
