| Abstract: | In order to solve the problem that with increasing the height of wind turbine tower, the mechanical properties, economy and constructability of common tapered cylindrical steel tower structure decrease, the design method for the lattice wind turbine tower using concrete filled steel tube （CFST） was investigated. Through taking a 3MW wind turbine as an example and adopting the unified theory of CFST and simplified space truss method, the lattice tower using CFST to meet the performance requirements was designed. And the structures of limbs, web members and nodes were given. Based on ANSYS finite element software, the mechanical properties and steel dosage of both lattice tower using CFST and tapered cylindrical steel tower were analyzed. The results show that the lattice tower using CFST with three limbs is feasible in the design method, and has excellent mechanical properties and better economy. |
