Unreinforced masonry (URM) walls are prone to failure when subjected to out-of-plane and in-plane loads. The development of effective and affordable strengthening strategies is a need. In this context, fiber reinforced polymer (FRP) materials offer viable solutions to solve or lessen the effects of overloading. This paper describes FRP systems proposed for use in the strengthening of masonry elements as well as the impact of such systems on the building being retrofitted. Also, field applications, some potential and others already implemented applications, are described. Field applications include strengthening for natural hazards (i.e. earthquakes and high wind pressures) as well as man-caused hazards (i.e. blasting). The potential of FRP systems for retrofitting of historic structures is also illustrated. Finally, research needs in this area are discussed.

Abstract
Unreinforced masonry (URM) walls are prone to failure when subjected to out-of-plane and in-plane loads. The development of effective and affordable strengthening strategies is a need. In this context, fiber reinforced polymer (FRP) materials offer viable solutions to solve or lessen the effects of overloading. This paper describes FRP systems proposed for use in the strengthening of masonry elements as well as the impact of such systems on the building being retrofitted. Also, field applications, some potential and others already implemented applications, are described. Field applications include strengthening for natural hazards (i.e. earthquakes and high wind pressures) as well as man-caused hazards (i.e. blasting). The potential of FRP systems for retrofitting of historic structures is also illustrated. Finally, research needs in this area are discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
