Historical Steel Shape 16x12BR110, or 16BR110 Canada

[CABaker]

Good day. I'm looking for some help on determining a reference for the historical steel shape 16x12BR110 as noted in the subject line. I've come across it from a circa 1953 steel drawing from Canada and the BR is stumping me. Going to the usual sources (AISC, CISC, Bethelehem Steel) I can't seem to find it. Does anyone recognize the shape designation? Most of the building is rivet steel.

This App supposedly has the Canadian beams listed. I don't have the canadian App so I can't check it for you. Try contacting their web site to see if your beam is listed.

Still no luck.

I was going to pop off with Bar, Round (Round Bar) but the rest of the designation is modeled after the typical WF/I/W/T type of designation: family (depth of member) x weight/length. (Check me on that: when did Canada switch to/from the English feet-inches-pounds designations?)

Could it be a HSS (tube steel) 16 deep x 12 wide x 110 lbs/ft to specify the thickness of the folded (bent) steel walls?

Section is definitely not HSS. I'm thinking it was a custom built-up riveted section detailed on a drawing long discarded. I was hoping someone else may have run across the designation previous.

I suppose as a side discussion, there is a mis-conception that Canada exclusively uses the metric system. A lot of us are around who were trained in Imperial units (by UK engineers that came over in the late 60's early 70's) and stick with it where possible, particularly with additions to existing buildings originally layed out/designed in feet-inches. Great way to confuse the young guys who have never heard the term 'kip' - don't laugh it happens a lot, I guess they don't teach that much in the schools up here anymore.

By the way, your thread here is the only time I have ever seen Google return only one location to a search inquiry.

Can't remember exactly, but officially, it was probably some time in the early 1970's. CSA Standard S16-1969 is Imperial while CSA Standard S16-M78 is Metric (SI System). In 1970, the Canadian government stated that the eventual conversion to the metric system is an objective of Canadian policy.

It took many engineers a long time to convert to the new system. In fact there are still a few engineers in Canada who use the Imperial system. I believe Steel Handbooks can still be purchased in the Imperial system.
