Research issues related to the appropriate use of FRP in concrete structures

This paper describes recently-completed research at the University of Bath within the BRE Centre of Innovative Construction Materials in the field of fibre-reinforced polymer (FRP) materials for use in concrete structures. The research described has been carried out in collaboration with Parsons Brinckerhoff, Bristol. The use of FRP to strengthen concrete structures is a mainstream technology throughout the world, and specific research projects aimed at better understanding the underlying mechanics of this technique are described here. Further, the use of FRP to internally reinforce concrete structures is described in the context of effective use of all materials, coupled with the assurance of ductile behaviour.
