Old WF Beam section

[pbc825]

Hi All,

I'm working on a project in a building constructed in the late 1950's. Three beam sections are no long standard sizes. Specifically the following:

8WF17
10WF21
12WF27.

Does anyone have access to the depth, flange width, web thickness, and flange thickness for these sections?

Thanks in advance.

From AISC 7th...

W8x17, d=8, bf=5-1/4, tf=5/16, tw=1/4
W10x21, d=9-7/8, bf=5-3/4, tf=5/16, tw=1/4
W12x27, d=12, bf=6-1/2, tf=3/8, tw=1/4

8WF17
d = 8
bf = 5.25
tf = .308
tw = .23

10WF21
d = 9.90
bf = 5.75
tf = .340
tw = .24

12WF27
d = 11.96
bf = 6.497
tf = .400
tw = .237

Much appreciated. Thank you.

if you are an AISC member, you can download old steel manuals, which define all the shape properties.

Looks like they have discontinued my favorite sizes. Makes me feel old. But then I am.

Us young'uns gotcha covered hokie; 8WF17 is pretty much a W8x18, 10WF21 is a good one (saw a lot of these in mills) but the W10x22 has notably better flexural properties for the low, low cost of 1 plf, and the W12x26 is almost the same flexural properties as 12WF27 but 1 pound lighter.
