| Abstract: | This paper presents experimental details on the effectiveness of textile reinforced concrete (TRC) as a structural strengthening material under flexure and shear. Two types of specimens, namely, plain concrete beams and reinforced concrete beams are strengthened with U-wrap configutation of TRC. Two types of fabrics having different weight per unit area are used for the investigations. Strengthened plain concrete beams are tested under three-point bending to investigate the flexural load carrying capacity, mid-point deflection and failure pattern. Further, experimental investigations are carried out on shear deficient RC beam strengthened with TRC as U-wrap under monotonic and low cycle fatigue loading. It is observed that under monotonic loading, there is about 19% increase in ultimate load carrying capacity and 852% increase in energy absorption for strengthened beam compared with un-strengthened beam. When the strengthened beam is subjected to low cycle fatigue loading, there is 20% reduction in ultimate load carrying capacity. But the ultimate deflection and failure pattern is found to be similar in both the cases. |
