Abstract

The wind field and the dynamic responses of a typical transmission tower line system under the typhoon"Seagull"were measured by the anemometer

strain gauges and the accelerometers in September

2014.Based on the measurement data

the characteristics of the random spatial wind field of the typhoon was analyzed

including the mean wind profiles

the wind direction

turbulent density

turbulent scale

power spectrum density of fluctuation

as well as the gust response factor of the dynamic strain responds on column of the tower.Then

the wind resistance reliability of the tower was estimated.The data and the analysis can be the references for the wind resistant design of the transmission tower lines system.
