Abstract Transmission tower is an important power equipment for transmission line, the damage and collapse of transmission tower happen occasionally caused by typhoons on the coast of China during these years. In order to study the wind load of the tower, a research method of the wind load characteristics of the tower based on wind tunnel test was proposed. The segmented full-size tower models were used as the wind tunnel test models, the experimentswere conducted with different wind speeds and wind angles, the variation of the wind loads was obtained. The results show that the wind loads change with the wind speed exponentially at low wind speed, and the basis of the exponential function is different in different models; the wind loads is a sine function over the wind angle, and the period and amplitude of the function is different in different model; the longitudinal force on different parts of the tower changes distinctly with different maximum value according to the fitting function. The tests results are of some reference to the design of transmission tower.

Key words： Transmission tower wind tunnel test segmented full-size tower model wind loadcharacteristics wind angle
