| Abstract: | The evaluation of dynamic characters of electrical transmission tower-line system with a big span is a key step for its wind resistant and seismic resistant design.On the basis of some related references,this paper has founded a calculation method of multi-degree-of-freedom to analyze the dynamic characters of coupled vibrations of electrical transmission tower-line system.In the mean time,an engineering example of an electrical transmission tower-line system with a big span is analyzed.Finally,the effects coupled vibrations of electrical transmission tower-line system on the dynamic characterictics of tower and line respectively are evaluated,and some conclusions are drawn. |
