| Abstract: | Based on the Sanjiangkou Yangtze River 500 kV large span transmission tower,its three-dimensional finite element model is built in SAP2000.And the dynamic analysis is carried out;and the first free vibration period and mode coefficient are obtained.Lastly,the wind-induced vibration coefficient of the tower is confirmed;and it is used in the wind-resistant design of the large span transmission tower. |
