Canadian Steel 350W
Canadian Steel 350W
(OP)
Our design criteria calls out for the use of CAN/CSA-G40.21 Grade 350W structural steel. I know that this is equivalent to 50ksi for Fy, but what is Fu? For the life of me I can not find it online or in any books in our office library. Our office just ordered the CISC handbook, so I wont have that for another week or so. Thanks.

Merci beaucoup

"Here is the table of characteristics of Grade 350W steel.
Good luck."
350w steel is essentially 50 ksi yield strength. Fu is the ultimate strength. Fu for this is around 65 ksi.
Let me know if you need anything more- Canadian steel is great :)

RE: Canadian Steel 350W
In fact S16-01 clause 5.1.3 states that structural steel shall meet the requirements of CAN/CSA G40.20/G40.21 or ASTM A992/A992M.
If you look through the G40.20 standard (which is only 47 pages and defines shapes, tolerances etc) it heavily references the ASTM standards. ASTM A6/A6M mostly.
If you look through the G40.21 standard (which is only 46 pages and talks about the steel material) it heavily references the relevant ASTM standards. Clause 4.1 also states that "Materials conforming to ASTM A992/A992M conform also to this Standard."
I'm not certain how 300W fits into this or other grades of steel. My hunch is that it is much the same.
Yup Fu = 450 MPa is what I typically use for connection design with 300W and 350W. Table 6-3 of the handbook has that information.
