Seismic vulnerability is defined as the amount of damage and loss incurred by a class of buildings with respect to the intensity of the ground shaking. It is represented by vulnerability functions of the mean damage factor defined as the ratio of the repair cost to the total replacement value. A simplified method is presented for development of vulnerability functions allowing for systematic quantification of uncertainties. The developed method was applied to stone masonry buildings in Old Quebec City, Canada. Vulnerability functions were developed using capacity curves describe the nonlinear lateral behavior of the building, and displacement fragility curves representing the probability of exceedance of a specified damage state under various levels of structural response. Parameters considered in the analyses are: displacement response, elastic damping, structural degradation factor, and the damage factors assigned to different damage states.The conducted sensitivity analysis showed that the mean damage factor is most sensitive to uncertainties in the capacity and displacement fragility curves. © 2013 Taylor & Francis Group, London.
