| Abstract: | Based on the basic features of fluctuating wind and Davenport wind speed spectrum, a number of wind load-time history curves are simulated by using the weighted amplitude wave superposition （WAWS）meth0d. In this paper time-history analysis in time domain to the transmission tower-line system of wind-induced response is done and power spectrum density and coherence function for the fluctuating wind pressure and wind vibration coefficient of the coupling model of four-wire-three-tower suspension tower are presented by numerous numerical simulation and statistical analysis. |
