| Abstract: | Based on the experimental result,the formula of deflection was present,and the key coefficients of the formula were determined.Furthermore,the calculations of the formula were compared with the test results of the flexure specimens strengthened with varied prestressed FPR laminates,to verify the correctness of it.The comparison showed an excellent agreement between the calculations and the experimental results,which indicated that the formula can be used to predict the deformation of the reinforced concrete flexure structure. |
