| Abstract | A framework for quantitative assessment of regional seismic risk of unreinforced masonry buildings is presented. It considers region-specific inventory of buildings, definition of the seismic hazard and
evaluation of respective vulnerabilities. Structural vulnerability is derived from the fragility functions relating the intensity of the seismic motion to the expected damage. The old historic center of Quebec City, Canada, a UNESCO heritage city,
was selected as a study area due to the concentration of masonry buildings and their high heritage value. An inventory of the structural characteristics of these buildings was conducted and the respective capacity and fragility functions were
developed and validated against empirical fragility functions based on damage data observed during past earthquakes. The proposed framework was then applied to assess the seismic vulnerability of the old historic center. Results for a scenario event
of magnitude 6.2 at hypocentral distance 15 km indicate that approximately 39% of the stone masonry buildings and 33% of the brick masonry buildings would suffer various levels of damage. |
| Summary | (Plain Language Summary, not published)
Built to resist gravity loads only, masonry buildings generally offer poor resistance to lateral seismic loads. This study proposes a method for
evaluation of the seismic vulnerability of masonry buildings. The Old Quebec City was selected as study area. |
