Abstract:
Aimed to ultra high voltage(UHV)long-span transmission tower being characterized with long-span, high-rise and heavy load, material selecting, conductor arranging and dynamic characteristic and wind-induced response, 1 000 kV UHV double circuit long-span towers were analyzed. Dynamic characteristics of these kinds of long-span transmission towers were summarized. Wind-induced vibration coefficient were calculated based on the wind load time history response, and according to the analysis of dynamic behavior, a reasonable wind-induced vibration coefficient in construction design was proposed. Results show that wind-induced vibration coefficient has discreteness and different values of coefficients should be chosen according to different heights of towers.The method can provide some references for the design of UHV long-span transmission towers.
