Research on Condition Assessment Method of Transmission Tower Under the Action of Strong Wind
Transmission towers are often subjected to the external damage of severe weather like strong wind and so on,which may cause the collapse due to the yield and fracture of the tower material.Aiming this issue,an assessment method was proposed in this paper to assess the operation condition of transmission towers under strong wind.With a reasonable assess index system established firstly,then the internal force of the tower material was solved and its stability was determined through the mechanical analysis of the transmission tower finite element model.Meanwhile,the condition risk level of the tower was finally determined by considering the difference among the influences of other factors like corrosion and loose of members,slope on the transmission tower through the analytic hierarchy process.The assessment method was applied to assess the wind-induced collapse of towers in 110kV BaoYiⅡ line in Wenchang City,Hainan Province,of which the result proves the method can assess the condition of transmission tower under strong wind and of guiding significance for improving the windproof capability of transmission towers.
