The Study on the Strengthening of Wind-Resistant for Transmission Tower in Coastal Areas

As the capacity of strong wind-resistant of the transmission tower for long running time is relative weak, the accident of tower collapses frequently occurred is a serious threat to the safe operation of the transmission line. Firstly the check and calculation of wind-resistant of the transmission tower were did, then the paper built the finite element model of the transmission tower to study the weak location with ANSYS software based on the practical engineering accident of PingzhaⅠdual loop transmission lines. Gusset plate model was created, through numerical analysis, the strengthening method was proposed for the capacity of wind-resistant of the transmission tower. This paper is of referring value for the bearing capacity increment of the same type transmission tower in coastal areas of multiple strong winds.
