I am looking at a building circa 1967 that some of the beams are labled 21B44.
I have looked in AISC's historical database, and this shape is not shown. I called AISC and they indicated that there might have been some manufacturer specific shapes at that time that was used. I have been doing a search and apparently there is a document called Bethlehem Steel Structural Shapes Catalog" from this era. Anyone know where to find it, or what the beam properties could be? There are a couple of other sectons like this as well.
Thanks.
