Therefore, seismic hazards for EHV transmission towers should not be underestimated. In particular, earthquakes are especially a significant threat to EHV transmission towers in Taiwan. Thus, this study establishes a quantitative risk assessment model for the seismic hazard analysis on the EHV transmission tower. Fragility curves of EHV towers were established by nonlinear dynamic analysis to describe the probability of structures at different damage levels caused by earthquakes. The damage level of an EHV tower after an earthquake can be accurately estimated by the proposed model, and emergency repair operations can be arranged. In addition, before an earthquake occurs, the proposed model can be used as a tool for estimate the damage potential of EHV towers. © ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2017.Fragility curve; Nonlinear dynamic analysis; Seismic hazard risk assessment; Smart grid; Transmission tower[SDGs]SDG7Dynamics; Earthquakes; Electric power transmission; Electric power transmission networks; Geophysics; Hazards; Risk assessment; Seismic design; Seismic response; Seismology; Smart power grids; Towers; Different damages; Extra high voltage; Fragility curves; Quantitative risk assessment; Seismic hazard analysis; Seismic hazards; Smart grid; Transmission tower; EHV power transmissionconference paper10.1007/978-3-319-61813-5_92-s2.0-85028699985https://www2.scopus.com/inward/record.uri?eid=2-s2.0-85028699985&doi=10.1007%2f978-3-319-61813-5_9&partnerID=40&md5=4f77cdccfc37ca2452a8b81c7ef1780d
