Résumé(disponible en anglais seulement)
This paper presents results from a seismic vulnerability analysis of the components of hydropower systems in Canada. A number of dams and their associated components (hydropower plants, switchyards, transmission towers, and supplementary equipment) at selected locations in western and eastern Canada were analyzed in the study. The seismic vulnerability for a given hydropower component was estimated by combining the probabilities of various levels of the seismic hazard at the component location, with the damage probabilities of the component corresponding to the seismic hazard levels considered. In this study, the seismic hazard was represented by the peak ground acceleration of the seismic motions. The calculation of the seismic hazard was based on the latest seismic hazard model
developed by Geological Survey of Canada. The damage potential for the hydropower components was represented by fragility curves. The seismic vulnerability for each component was expressed by the damage probability as a function of peak ground acceleration. The results from this study show that the most vulnerable components of a hydropower system are the switchyards and the power plants.
