Abstract:Fiber reinforced polymers (FRP) are investigated in this study in comparisonwith a new class of materials, textile reinforced mortars (TRM), for shear strengtheningand/or seismic retrofitting of concrete structures. Textiles comprise fabric meshesmade of long woven, knitted or even unwoven fiber rovings in at least two (typicallyorthogonal) directions. Mortars – serving as binders – contain polymeric additives inorder to have improved strength properties. In this study, experimental investigationswere carried out in order to provide a better understanding on the effectiveness of TRMversus FRP jackets as a means of increasing: (i) the axial capacity of concrete throughconfinement; and (ii) the load-carrying capacity of shear-critical reinforced concreteflexural members. From the results obtained it is strongly believed that the proposedTRM strengthening technique is a viable alternative to the already successful FRPstrengthening technique.
