Random Wind-induced Response Analysis of Transmission Tower-line System
Energy Procedia, 2012 AbstractIn order to research the the effects of conductor wires on transmission tower under wind load, considering the theory of flat cable assumptions, the vibration equation of transmission tower-line system under wind load was deduced. Using software ANSYS, The 3-D finite element models of single tower, one tower and two spans of conductor wires ...
