This paper discusses the flexural performance of RC beams with interface and joints. Experiments of RC beams with concrete members cast respectively and different types of connection methods were examined. The experimental parameters were the position of joints and types of connectors between concrete members. The results revealed that the crack distribution, the crack width and the opening of interface were affected by the joints. However, the flexural capacity of beams with different concrete members and connectors were in good agreement with the calculation values of normal RC beams.
