Depending on the age. There's a company that produces it now called ComSlab

I've not directly dealt with it, but I think it is a ribbed slab system constructed using metal form. Similar to the waffle slab, this type of construction had been popular for a while, for it reduces labor cost and can be used in repeat productions. The form had changed from metal pan to fiberglass, but enthusiasm had disappeared, part of the reason been the difficulty in form removal.

By the state of those two end beams a disaster in waiting would seem like a good description. ...

Assume the slab is cast first then the beams?

It maybe a TRUSCON FLORETYLE system.

I tried uploading a PDF file of the system from the early 1920's but it won't load - something wrong with the site. I will try again later today. You could try this link to archive.org Link for the same info.

The more I look, I think I have 2 different systems to look the same. The one that is rusted, the metal forms were left in place. Another location in the structure there is a floor crack, and it goes all the way through the floor. would not expect that with a metal form system left in place. I think they took them out some point, or at the get go.

JStructsteel:

If you go the document I linked in achive.org you will see that TRUSCON had a stay-in-place and a removable form system. So maybe they used both on your project. However, the removable forms in the photo below do not have the same rib patterns are yours - therefore may not be a TRUSCON system.

Somehow the rebars look like deformed steel, it might reveal the age of construction.

Or they didn't buy enough of the remain-in-place style. Since next day shipping probably wasn't an option (Amazon was still just a jungle and a river), they just used them as removable forms until they got the end, and then left them there.

.... until they got the end, and then couldn't get the form off. I've heard many interesting stories on removal of this type form.
