Practicality of composite wood-concrete floor systems

[Cadair]

Assuming that one could actually design it to work, how practical do you think a composite wood-concrete floor system would be? It would be a precast conc. slab with a perforated, embedded T shape with the stem sticking out. A glulam beam would then be ripped with a grove to receive the stem, which would be glued in.

Assuming all this could calc out to work, and somehow the wood would be protected from the concrete. How practical is this over just using a thicker precast slab or a composite steel-concrete floor? I know it is a very general question, but it isn't for a specific building.

You may end with a system that works and there maybe people wanting to buy it; I have seen sell things (absurd precast items) that I'd never think would be ever sold. But I don't think the matter is particularly advantageous; in the prefab way because you may be adding excesive weight, and in the in situ because will tend to less clean construction, maybe staining the wood work.

Sounds to me like a harebrain scheme. But then, I don't know why you are considering this.

Thanks for your posts. I heard about some research being done on this topic. I wanted some real peoples' opinions instead of academic...

I read a technical report recently on the use of timber and concrete composite bridge decks in Brazil. Is this of any use?
