Fiber Wrap Repair

[2457F]

Does anyone know where I can find a design example that shows the analysis process when using a fiber wrap on a concrete beam repair?

Here's something from a fiber wrap manufacturer. From past experience the manufacturer usually does the design.

Agree with it being done by the mfr in my experience. We gave them the amount of rebar, strength of rebar, and assumed rebar depth it would take which they then took and turned into an equivalent amount of wrap. They submitted calcs for our review as well.

Thanks for the information.

I have this book and find it to be full of useful examples: Link

Flexural or shear reinforcing? I might have a MathCAD worksheet from a homework assignment.

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.

Simpson Strong-Tie is getting into this market as well. Might want to contact them to see what they offer by way of design help and/or products.
