Abstract:
This paper deals with the theoretical and experimental study on the ultimate behavior of concrete members reinforced with AFRP rods under combined axial load and bending. This involving the tests on twelve model specimens subjected to eccentric tension or compression, contributes data on crack formations, ultimate strength, curvature variation and flexural rigidity deterioration. No marked difference from conventional reinforced concrete members could be observed. Ductility based on the rotational capacity of cross section and flexural rigidity after the formation of cracks were both relatively small. In cases where a certain amount of bond is maintained, even when the members are placed under axial forces, the estimation at least of the ultimate strength is thought possible by application of the beam theory with the term for the axial forces taken into account.
