Abstract | Strong earthquakes in Eastern Canada with major urban centers founded partially by soft postglacial sediments have high damage potential. The presented seismic microzonation for Québec City was
conducted in agreement with the provisions of the National building Code of Canada based on the available geological, geomorphological and topographical knowledge and existing boreholes logs, completed by geophysical and ambient vibration
measurements. To identify the most vulnerable infrastructure particular attention was paid to the city-owned buildings (105) and bridges (119). Structural properties were integrated with local geological and geotechnical data within a user-friendly
GIS system to provide Québec City decision makers and engineers with powerful quantitative and visual representation of potentially high risk facilities. For the seismic risk assessment at an urban scale, several seismic scenarios were generated with
typical moment magnitude (M) vs. rupture distance (R) combinations (e.g., M6.0-R10 km, M7.0-R30 km) obtained from the deaggregation of the seismic hazard. The inventory of assets at risk consisting of more than 16,000 buildings was developed using
sidewalk and virtual desktop survey techniques, and by interpretation of municipal property assessment databases through inference matrices. The vulnerability was determined using fragility data correlating directly to the ground shaking intensity to
five damage states: none, low, moderate, extensive complete. |
