n this paper, according to the domestic and foreign scholars on the research status of FRP concrete continuous beam, the mechanical performance of FRP and loading characteristics of FRP concrete beams, the following aspects are worked. This paper makes flexural property research by means of 3 FRP continuous beams and 2 FRP simple supported beams test, this test considers reinforcement ratio impact on the beams and measures cracking load, crack propagation law, midspan and support strain, and summarize the loaddeflection of FRP concrete continuous beams. Basing on the results of the test and the research of scholars at home and abroad, this paper calculates and analysis the ductility of the FRP concrete beams.
