Concrete Roof Penetration 1

[TobyT]

I recently read somewhere (don't remember where) a suggested max concrete core diameter in relation to the deck thickness. Has anyone seen this recommendation?

Does anyone know a publication which addresses the performance of concrete deck slabs with varying size full depth penetrations (with or without steel sleeves)?

Thanks.

Are you talking about a composite deck or a flat slab?

For composite deck, check out:

For flat slab, check out:

http://www.cement.org/buildings/tech_note_floor_openings.pdf

These are focused on larger penetrations but do have relevance to smaller ones.

Thanks.

Have any leads on information on penetrations in one way cast slabs (with beam supports)?
