Abstract
The safety of power transmission tower directly affects the supply of electricity. If the designed power transmission tower could not bear the strong wind, the collapse of transmission tower would lead to the power outage. In this paper, we analyzed the safety of transmission tower subjected to the strong wind of level 10 by using a finite element method. Commercial software Abaqus was used for simulating the mechanical response of transmission tower. Finite element model was introduced to complete the static analysis of truss structure. Ten kinds of cross-sections were chosen to assess the safety of transmission tower. According to the simulated results, both the maximum stress and the maximum displacement decrease with the increasing cross-section dimension. When the cross-section dimension is less than a certain value, the designed power transmission tower could not safe under the strong wind of level 10.
