| Abstract | A methodology is developed for first-order assessment of the seismic risk involving seismic hazard, local building inventory, and evaluation of respective vulnerability. Central to the vulnerability
analysis is the concept of fragility functions used to determine the probability of exceedance of a specified damage state, where the nonlinear structural behaviour is defined by capacity curves. A new set of continuous hazard-compatible fragility
functions is proposed for rapid risk assessment on urban and regional scales in interactive spread sheet application. To demonstrate the method, it was applied in a dense urban environment of downtown Quebec City, Canada, for damage assessment of
low-rise wood light frame and unreinforced brick masonry buildings. Earthquake scenario with M6.2 and distance 10km from the centroid of the study area was developed from deaggregation of the seismic hazard defined by the current National Building
Code of Canada-NBCC2010.Theground shaking was represented with a simplified site-specific response spectrum, fully defined with spectral accelerations at 0.3 and 1.0s. The results show that as much as 61% of the considered buildings would sustain
certain degree of damage. The influence of epistemic uncertainties in the ground motion prediction and the site-class on damage estimation is evaluated. |
| Summary | (Plain Language Summary, not published)
A rapid risk assessment method was developed involving seismic hazard, local building inventory, and evaluation of respective vulnerability. The original
method proposes a set of continuous damage functions expressed in terms of the intensity of the seismic shaking. It was applied so far for 2 types of buildings, but the algorithm is being developed for the whole set of 128 buildings types proposed by
Hazus. The same procedure is planned to be applied by the Analyse des riques d'aléa naturels - ARIANA rapid risk assessment tool. |
