Normal section of RC reinforced were analyzed. Through beam strengthened with Near-Surface Mounted (NSM) prestressed FRP the analysis method of the normal section of the coordination between the strain strength, cracking moment ,yield moment and ultimate moment formula were derived and optimized. Simple and practical formula was obtained. The calculated result agrees well with the experimental result, which is provided for future reference in research and design.
