RE: Concrete Joists

Get out your chipping hammer.  You may strike structural steel.

Often times in the 30's they used concrete as the fireproofing on structural steel. I have seen it on many 30's vintage projects. They used it on steel beams, girders, and steel trusses. Old books will give you thicknesses and fire ratings for structural steel.

I am doing a remodel to a 1930'3 concrete residence and came upon an unusual
(to me) framing system.

The floor slab is concrete which is supported on joists which look like
"fat" TJI's at 16" on center. At first I thought I was looking at a
fireproof spray on to a wood I joist, but they're real concrete. It was not
readily apparent whether the floor slab is monolithic with to floor slab but
they do seem to have been poured with the concrete girders.

Any idea what this may be? The house is apparently the work of a local Salt
Lake City "cement" man, but it's got me stumped.
