Hi all,
I am trying to find the properties of old steel members, can you please recommend a reference?
A beam: 12B22
and an open web joist: 146x-174F

I think AISC has all of the old manuals on their website. There's also the old steel shapes book, it's got a blue cover. I'm sure someone has that handy or remembers the name here.

For joists you should fill out the form on SJI's website.

Attached are the detailing and design properties for a W12x22. A W12x22 and a 12B22 are virtually the same member. My 6th ed AISC steel manual calls it a 12B22, but my 7th ed calls it a W12x22 with the same properties (some standard gages differ, but I doubt that would matter to you). A "B" beam is just a light beam, but AISC went away from that naming convention.

Link to AISC website where you can get old AISC manuals, but you do have to be an AISC member: [URL unfurl="true"]https://www.aisc.org/publications/historic-steel-construction-manuals/[/url]

Another link to AISC shape spreadsheets (these are free): [URL unfurl="true"]https://www.aisc.org/publications/steel-construction-manual-resources/15th-ed-steel-construction-manual/shapes-database-v15.0/[/url]

v15.0 has all the current AISC shapes. v15.0H has all the historic AISC shapes. In the v15.0H spreadsheet, you can find a 12B22 in row number 12975. It's not intuitive to find. It's entered as "B 12x4" and then the weight/ft is listed in column T.

Hope that helps. I don't have info on the joist.
