Things to consider when using FRP retrofit:
1) The assembly needs to be fire proofed which will add additional weight.
2) When used in areas with considerable temperature variations debonding will occur between the base concrete and the FRP.

Can somebody point me to a good source of info for using FRP "strips" to reinforce existing concrete?
Specifically I'm interested in strengthening an existing flat plate slab to add a new penthouse on top. The addition will also require a large number of 12" to 14" square penetrations for new mechanical units. I need some ballpark figures for a cost estimate ASAP.
I would appreciate any insight.
Thanks,
