ABSTRACT

The numerical simulation of transmission tower-line under wind is important owing to the increasing number of wind-induced accidents recently. In this study, the wind loads, based on the harmonic superposition method and Kaimal wind spectrum, was constructed by MATLAB software according to Shinozuka theory. The three-dimensional (3D) finite element model for transmission tower-line was established. In the present study, the dynamic behavior and the mechanism of a typical transmission tower-line under wind is followed with great interest. The numerical simulation results showed that the displacement spectrum in the low frequency (0.1-0.5 Hz) was excited and the response of structure is remarkable, meanwhile the range of frequency is similar to that of wind spectrum. The displacement spectrum in 3Hz was excited, due to the main frequency of structure. The proposed method can be successfully performed and utilized on more structures.
