Analysis of Effective Strain of FRP Pasted on Surface of Reinforced Concrete Bending Member

A lot of test data from many domestic and foreign articles about concrete bending and shearing beam reinforced with FRP was collected and analyzed. Through the statistical analysis of test data and comparative analysis of the theoretical calculation based on the current standard and the existing calculation model, the size of ultimate strain of bending beam and shearing beam reinforced with FRP was shown.It was found that the effective strain of most test members was less than the lower limit value of current design code.It was suggested that in practical projects, for bending and shear reinforcement with FRP ,effective strain were not less than 0.006, 0.004 respectively.
