Abstract: The invention relates to an FRP (fiber reinforce plastic) tube-concrete-steel tube combined tube tower comprising an inner steel tube, an FRP outer tube and a concrete layer, wherein the inner steel tube is formed by connecting a plurality of steel tube segments, the FRP outer tube is formed by connecting a plurality of FRP tube segments, and the concrete layer is poured between the inner steel tube and the FRP outer tube; the adjacent steel tube segments of the inner steel tube are connected by a steel tube adapting piece; the steel tube adapting piece is positioned on the outer surface of the inner steel tube; the adjacent FRP tube segments of the FRP outer tube are connected by an FRP adapting piece positioned on the inner surface of the FRP outer tube; and the steel tube adapting piece and the FRP adapting piece are both embedded in the concrete layer. The invention also provides a segmented construction method for the FRP tube-concrete-steel tube combined tube tower. When the combined tube tower or similar tower-shaped or columnar structure is implemented, long tubes and large prefabricated concrete parts do not need to be transported The combined tube tower has high construction speed, the steel tube adapting piece and the FRP tube adapting piece can also serve as shear keys between the concrete layer and two tubes and the stiffening ribs of two tubes, thus improving the structural property of the combined tube tower.
