The flexural performance of reinforced concrete beams (RC) strengthened by prestressed aramid fiber reinforced plastic (AFRP) sheets with permanent anchor have been tested and shown in companion paper (Deng & Xiao 2010). Based on sectional analysis, the formulas for calculating the bearing capacity of beams strengthened with prestressed AFRP sheets were established in this paper. By these formulas, the theoretic results of cracking, yield and ultimate moments and its corresponding deflections at these points were derived and compared with the experimental test results of beams. The comparison analysis show that, the analytical results of tested RC beams are in coincidence with the experimental results.
