| Abstract | The collapse of a transmission tower under wind action is studied in this paper. A three-dimensional finite element model of the transmission tower is established based on a real project. The birth-to-death element technique is adopted in ABAQUS/Explicit. Kaimal fluctuating wind power spectrum and the harmony superposition method are used to simulate the fluctuating wind speed time history. The dynamic behavior and the collapse mechanism of the transmission tower under three different angles of attack α = 0, 45 and 90 are carried out, respectively. The results show that the collapse of the transmission tower at 45 angle of attack occurs easily, but it is contrary at 90 angle of attack. The fracture position of the transmission tower under wind excitation is obtained, and the initial damage of the members happens simultaneously in the main and the secondary element. The results of the collapse analysis can provide reference to the design of the transmission tower and the reinforcement of this structure to prevent the collapse of the tower. |
