• Resumen

  • The main objective of this work is to study the long-term and residual flexural strength of Near Surface Mounted (NSM) strengthened Reinforced Concrete (RC) beams with Carbon Fiber Reinforced Polymers (CFRP) strips when subjected to sustained loading. This work involved twenty-eight RC beams divided into two series, A and B, with two concrete batches of different compressive strength. In each series, some of the beams were strengthened with CFRP strips using the NSM strengthening technique and the others were un-strengthened. Series A was divided into two groups, A1 and A2, while series B was divided into three groups, B1, B2, and B3. The beams of the first group in each series were tested at age of 55 days to determine the short-term flexural behavior of un-strengthened and strengthened beams. Other groups were subjected to long term test with different sequences.
