摘要

For un-cracked reinforced concrete beam with FRP, the adjusted effective modulus theory (AEMM theory) is applied and the calculation method of internal force and stress redistribution of various materials under creep is given with the transformed section method. A comparative analysis is carried out from height change of the concrete beams, reinforcement ratio, FRP layers and the initial stress. The stress of the bars and FRP will increase over time and the degree of increase will be more obvious with the height of the beam and the reinforcement increased, but the concrete stress will be reduced accordingly. The conclusion plays an important role for the performance evaluation of the long-term stress and deformation of concrete beam reinforced with FRP.
