Abstract Downburst event is identified as a major cause to failure of transmission lines in non-coastal regions. In this paper, a novel nonlinear analytical frame
for quasi-static buffeting responses of hinged and multi-span insulator-line systems are derived based on the theory of cable structure. The closed-form solutions
are presented and applied to predict nonlinear response including displacements
and other reactions of the system subjected to a moving downburst wind in a case
study. Accuracy and efficiency of the derived analytical frame are validated via
comparisons with results from finite element method. More >
