Abstract This paper presents the results of short span concrete-filled fiber reinforced polymer (FRP) tubes filled with different recycled coarse aggregate (RCA) replacement ratios. The mechanical response of recycled concrete-filled FRP tubes (RCFFTs) under flexural load was examined to investigate the influence of RCA as an in-filled material. The experimental results were compared with the simplified finite element model to estimate the failure behavior of the test units. RCFFTs with a 100% RCA replacement ratio showed a similar bending behavior compared to natural aggregate concrete-filled FRP tubes. The flexural behavior of 100% recycled aggregate concrete could be complemented and utilized because of the high strength and high stiffness of the FRPs.
