Abstract: The invention relates to a novel FRP (fibre-reinforced polymer)-concrete-steel double-wall combined tubular beam and a beam-slab combined structure adopting the same. The double-wall combined tubular beam comprises an FRP outer tube, a steel inner tube and concrete filled between the FRP outer tube and the steel inner tube, wherein a plurality of shear connectors are arranged at one side of the steel inner tube where the concrete is consolidated; and the steel inner tube can be eccentrically arranged toward the tension side of the combined tubular beam relative to the FRP outer tube. The beam-slab combined structure comprises (1) a beam-slab structure formed by the double-wall combined tubular beam and a lightweight corrosion resistant slab (like an FRP or aluminium slab) arranged on the double-wall combined tubular beam; and (2) a beam-slab structure formed by the double-wall combined tubular beam and an FRP bar concrete slab, wherein the upper part of the double-wall combined tubular beam is combined in the bottom layer of the FRP bar concrete slab to form a whole body. The combined tubular beam has very good corrosion resistance, low cost, light weight and good ductility and can be constructed and connected with other members easily.
