Research on the Wind-induced Vibration Coefficient of Transmission Tower-line System
Physics Procedia, 2012 AbstractThe six different non-linear finite element model of the transmission tower-line system which have different spans and different height difference was established by the finite element analysis software, and wind velocity time series with resorting to weighted amplitude wave superposition (WAWS) was simulated.
