Corrugated arch concrete steel floor

[nr123]

Anyone familiar with this type of floor? Or aware of any reference materials?
I’ve done a lot of searching and have seen a few pictures but that’s about it.
The building is early 1900s I’d say. The arched corrugated panels span about 4-6’ to what I surmise is a jr beam beam cast into the concrete. The jr beams span about 8-10’ and bear on large plated beams and girders.

First I've seen it... thanks. Early 1900s was near the beginning of reinforced concrete.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

Found some info possibly. Going to start using it as a base for searching keywords. Maybe a variation of a Roebling floor system. Still digging.

I don't know why the concentration of rivets at the end of the beams, unless to resist the reaction that KootK aluded to in an earlier thread... the loading would give almost a uniform SFD... The rivets for the supporting 'purlins' appear to be a much smaller diameter... Lovely structure... historic quality.

That is similar to what we would call a "jack-arch" system in the bridge world. Here is an interesting paper where one was tested to failure.
