Seismic risk assessment of mega-thrust Mw9-class subduction earthquakes and aftershocks in Victoria, British Columbia, Canada using multi-variate seismic demand models

International Conference on Applications of Statistics and Probability (12th : 2015 : Vancouver, B.C.)

This study extends current seismic demand estimation methods based on incremental dynamic analysis by characterizing dependence among different engineering demand parameters using copulas explicitly. The developed method is applied to a 4-story non-ductile reinforced concrete frame in Victoria, British Columbia, Canada. The developed multi-variate seismic demand models are integrated with a story-based damage-loss model to assess the seismic risk due to different earthquake loss generation modes (i.e. non-collapse repairs, collapse, and demolition). Results obtained from this study indicate that the effects of multi-variate seismic demand modeling on the expected seismic loss ratios are significant. The critical information is the limit state threshold for demolition. In addition, consideration of a realistic dependence structure of maximum and residual inter-story drift ratios can be important for seismic loss estimation as well as for multi-criteria seismic performance evaluation.
