STRENGTHENING OF CANTILEVER AND CONTINUOUS BEAMS USING NEW TRIAXIALLY BRAIDED DUCTILE FABRIC
Effectiveness of a new triaxially braided ductile fiber reinforced polymer (FRP) fabric for flexural strengthening of cantilever and continuous reinforced concrete beams is examined. The behavior of beams strengthened with the new fabric was investigated and compared with the behavior of similar beams strengthened with a commercially available carbon fiber sheet. The responses of the beams were studied in terms of deflections, strains, and failure modes. The beams strengthened with the new fabric showed greater ductility than those strengthened with the carbon fiber sheet. The new fabric provided reasonable ductility due to the formation of the plastic hinges that allowed for the redistribution of the moment between the positive and negative moment zones of the strengthened continuous beam. Redistribution of the moment enabled the full use of the strength of the beam at cross sections of maximum positive and negative bending moments.
