FRP over an existing plastered wall?
(OP)
Hello community,
I have an existing 1940's concrete frame system with infill brick for the entire elevation(two leaf with a 25mm air gap in between). I am considering installing FRP at the base floor to halt potential soft-story effects when the infill fails . The issue is that there is an existing cement plaster render on both sides of the infilled frame. My question is what do you think of installing FRP over the plaster rather than chipping out all the plaster where this will go? I think applyying FRP to the existing brick is always ideal but in terms of shear transfer, im sure i can transfer shear forces from the conc frame to the FRP, the plaster is only bracing the FRP. Thoughts?

I'm just going to have blow out the plaster and install FRP, I can sleep better that way.

Actually my situation is a bit unique in that my client's property is half of an existing structure. If I stiffen up the elevation in the way you are talking about, then i am introducing eccentricity in a big way because i have ability to equally stiffen up the elevation on the neighbor's side of the building. I am only trying to introduce ductility into the existing system rather than stiffen it up and have it attract more load (it's founded on a rock, so ground has stiff period already).
