Abstract: The application of recycled concrete in civil engineering was an effective method to resolve the problem of dealing with a large amount of construction waste. The recycled concrete beams were investigated in this paper. The RC beam flexural capacity calculation formula dependent on the replacement ratio of recycled aggregate was founded, which was based on the theoretical analysis according to the design code of concrete structures. And the M-j relation curves of the RC beams were calculated by the numerical method. The results showed that the results of theoretical calculation accorded well with the existed experimental results of recycled concrete beams at home and abroad. Variance Analysis proved that the theoretical analysis method and numerical analysis method were both applicable. The reliability analysis of flexural capacities of RCA beams was given. The influence of different factors on the reliability index was studied. This research provided much valuable references for the design of recycled concrete beam.
