| Abstract: | By means of a concrete creep model deduced to a formula for calculating the creep of reinforced concrete beams strengthened with CFRP.Analysising the creep basis on this formula and setting down the concrete beam neutral axis,and it's the impact of the deflection of the concrete beam.The results of this study have practical value to the application and design safe of CFRP for concrete structure in future. |
