References for back propping

[oranda]

Can anyone suggest where I can find references about back propping design of RC slab/beam? I just don't know too much about it with regards to how loads from supporting slab are distributed to the floors below and how far you would need to provide back propping.

Your help would be appreaciated.

Thanks

ACI uses the term re-shoring or back-shoring.

Here's some links to some sources:

Reshore 1

Reshore 2

Reshore 3

Reshore 4

Reshore 5

Most reshoring is based on ACI 347 (see Reshore 3 above). These are simply a few links from Google based on the keyword "reshoring" or "reshore".
