Primarily, the composite materials currently used in the pole tower are glass reinforced plastic (GRP) composite materials, which is composed of reinforced fibers and resin. Main disadvantages of pole towers of existing composite materials: small elasticity modulus of composite materials and relatively great tower body deformation. Based on the theoretical calculation, a pole tower of bamboo joint bionic composite materials is put forward in this paper. Compared with the pole tower of conventional composite materials, the power transmission pole tower of bamboo joint bionic composite materials not only has all advantages of pole tower of conventional composite materials, but also improves the stiffness and wind resistance deformability of pole tower of composite materials. Meanwhile, the bamboo joint shape may be in harmony with the urban landscape environment, has more good-looking appearance, and is especially suitable for the areas characterized by highly urbanized expansion, dense population and narrow power transmission corridor.
