Timothy:

 

We’ve had to use this material for several projects due to screw ups in the field.

 

The design is done by the supplier and based on every set of calcs I’ve seen, is

Based on simple “mechanics of materials” principles.

Subject: FRP Reinforcement

 

When reinforcing an existing concrete beam with FRP, do we just design for a brittle failure since it doesn’t yield?  I know ACI has a document but I don’t have it and I want to confirm that designing the reinforcing is a matter of simple mechanics, as with normal steel reinforcing.  Is there anything I’m missing?

 

I just need enough to explain to our client how we want to do it.
