Abstract

The author reviews experimental studies which have provided fundamental knowledge on the use of a new generation of composite materials, namely textile-reinforced mortars (TRM), as strengthening and seismic retrofitting materials of concrete and masonry structures. TRM jackets are investigated as a means: to provide confinement in plain and reinforced concrete (RC), to increase the shear and flexural resistance of RC members, to increase the deformation capacity of old-type RC columns subjected to simulated seismic loading and to increase the out-of-plane or in-plane strength of unreinforced masonry walls. In all cases, the effectiveness of TRM systems is quantified through comparison with equivalent fibre-reinforced polymer (FRP). Based on the results it is concluded that TRM jacketing is an extremely promising new technique, which will enjoy the attention of the research community and will be employed in numerous applications in the next decades.
