| Abstract: | In order to provide for the national production and consumption, it is of practical significance to ensure the safe and reliable operation of the transmission tower-line system, as part of the infrastructure. The statistics of multiple earthquake disasters show that the system is highly vulnerable during seismic motions. We summarized research progress of the transmission tower-line system from aspects of dynamic analysis models of seismic response, numerical simulation and shaking table model test, and analyzed the characteristics and the existing deficiencies of dynamic analysis models and the research methods. And then the key issues needing immediate attention and the research prospect of seismic response analysis methods of transmission tower- line system were addressed, which laid the foundation for further study. |
