Welded Wide Flange (WWF)
Welded Wide Flange (WWF)
(OP)
I am working with some old drawing from '67 that use the WWF designation. As far as I could find, all of the current WWF designations are no where close to what I am dealing with. So my question is, where can I find specs on old WWF designations. Eg: 36 WWF 118, 27 WWF 89, 18 WWF 105, etc.
Thanks in advance.
Thanks in advance.

The designation for wide flange is WF and not WWF. Isn't WWF a common acronym for welded wire fabric? It could be the Canadian designation like Lutfi suggests, but I'm not familiar.
In the US, the closest sizes to ones listed are 36WF135, 27WF84. 18WF105 is listed in AISC 6th Edition.

Thanks for you replies
RE: Welded Wide Flange (WWF)
WWF = Welded Wide Flange
versus
WF = Wide Flange
and of course
WWF = Welded Wire Fabric
for the concrete guys & gals out there
if the WWFs are actually Canadian sections, then i would consider analyzing as CSA grade 40.8 - or 40 ksi, 280 Mpa yield.
Having said that, if the beams were kicking around for a while in a shop before being used, they could be as weak as 33 or even 30 ksi (if its an old grade).
