| Abstract: | Taking the project of Xijiang 500kV four circuits on one large-span transmission tower as an example,the structural design of the large-span transmission tower was introduced.Davenport wind speed spectral density function was used to simulate wind speed of the large-span transmission tower-line system.Using direct integration Newmark method,numerical simulated wind speed time series was employed to investigate the wind-induced vibration of the large-span transmission tower-line system.The recommended value of wind vibration coefficient was proposed and compared with its value of wind tunnel experiment.The results can be used as a reference for similar large-span transmission tower. |
