Abstract


  • Fibre-reinforced polymer (FRP) jackets have been widely used to confine concrete columns to

    enhance their load-carrying capacity and ductility. More recently, the use of FRP jackets to

    improve the performance of hollow steel tubes and concrete-filled steel tubes has also been

    explored. This paper presents the results of a recent experimental study in which the behaviour

    of FRP-confined circular concrete-filled thin steel tubes under axial compression was examined.

    The experimental study included three series of tests and was focussed on the effects of the

    diameter-to-thickness ratio of the steel tube and the confinement stiffness of the FRP jacket.

    The test results revealed that the FRP jacket either substantially delayed or completely

    suppressed the local buckling failure mode of the steel tube. As a result, the compressive

    behaviour of the concrete-filled thin steel tube as well as the concrete is significantly

    improved in terms of both strength and ductility.
