Seismic retrofitting of RC walls externally strengthened by flax–FRP strips

Several studies available in the literature have demonstrated that natural fibres can be employed in externally bonded (EB) fibre-reinforced polymer (FRP) strips used to strengthen existing reinforced concrete (RC) members. The study aims to demonstrate the feasibility of retrofitting RC walls using flax–FRP (FFRP). The study consists of an experimental campaign and analytical evaluations, the latter aimed at determining the evolution of...
