Abstract


  • Hybrid FRP-concrete-steel double-skin tubular columns (hybrid DSTCs) are a new form of

    hybrid columns developed at The Hong Kong Polytechnic University. They consist of an

    outer tube made of fibre reinforced polymer (FRP) and an inner tube made of steel, with the

    space between filled with concrete. In these hybrid DSTCs, the three constituent materials are

    optimally combined to achieve several advantages not available with existing forms of

    columns, including their superior corrosion and seismic performance. This paper presents the

    test results of a series of large-scale hybrid DSTCs subjected to combined axial and cyclic

    lateral loads, with an emphasis on the effect of a high strength concrete infill. All column

    specimens had a circular section with a diameter of 300 mm and a height of 1350 mm (from

    the point of lateral loading to the top surface of the stiff RC footing). The parameters

    examined include the concrete strength, the confinement stiffness of the GFRP tube and the

    axial load ratio. The test results showed that these hybrid DSTCs possess excellent ductility

    and hence excellent seismic resistance even when high strength concrete with a cylinder

    compressive strength of around 120 MPa is used.
