Background to the European seismic design provisions for retrofitting RC elements using FRP materials

This paper is a comprehensive state of the art background document on European seismic design provisions which was assembled in support of the development of design guidelines by the fib Committee 5.1 regarding the use of externally applied Fiber Reinforced Polymers (FRP) materials in the seismic retrofitting of reinforced concrete structures. In the context of developing design guidelines, the underlying mechanistic models that support the derivation of provisions were assembled after critical evaluation of the existing proposals and with careful reference to the available experimental evidence, the comparative assessment of past models in the literature, and requirements established from first principles.JRC.G.4-European laboratory for structural assessmen
