| Abstract: | In this paper, the seismic behavior of the electric cable bridge in certain nuclear power station engineering was analyzed by the commercial finite element software, ANSYS. The analysis includes the dynamic characteristics and the reaction spectrum analysis of the structure under seismic loads. The results indicate that the structure of electric cable bridge is secure under the seismic loads. This mthod and results can also be extended to other structure of electric cable bridges. |
