Historic shapes pre-1930's 1

[aiden]

I am evaluating an existing building in Canada and I encountered steel shapes that I could not find in any available references. not even in 1934 AISC, old CISC handbook etc.

the beam shapes are mostly 27I160, 27I145, 27I101, etc. (note that I/S shapes commonly comes up to 24" only, even in older AISC databases). I have also smaller sized I shape beams, 18, 12, etc. but does not nearly match in any shapes database. Columns are problems too, 12H75, 12H40, 12H100, 12H130.

field measurements can be a bit difficult, over 80 years the steel beams and columns had been coated several times with thick coating to prevent very high corrosive attack from sulphuric acid (a 99% pure H2SO4 plant).

could anyone have these kind of I and H shapes database? or at least what steel mills these shapes came from?

I'll see what I can dig up... brought in a couple of books... they were stored in cold and I'm waiting for them to warm up... put them in zip lock bags to keep condensation off. Use the same method for my 35mm camera...

aiden - I have information on Carnegie shapes from 1923 and Pencoyd from 1892 on my website (link below, both documents are on the home page). Perhaps they may help.

Just checked... the texts do not contain member tables. Are there any rolling mill marks on the webs. Many old sections have rolling mill stamps rolled directly into the section.

The following book might have what you're looking for:

"AISC Rehabilitation & Retrofit Guide, A Reference for Historic Shapes & Specifications"; Steel Design Guide Series 15.

The "H" sections are there. They are listed as Carnegie Beams (CB). There are no 27-inch "I" beams but there are 27-inch Carnegie Beams and wide-flanges with the same weight.
