AbstractSeismic risk assessment integrates seismic hazard, exposure and its vulnerability. Vulnerability describes the potential of damage and loss incurred by a class of buildings as a function of the intensity of the ground motion. It is represented by: fragility functions that correlate seismic input to the expected damage, and vulnerability functions that represent damage factor defined as the ratio of the repair cost to the total replacement value. This paper focuses on the development of a procedure for rapid damage assessment intended for informed emergency management in the minutes following a strong earthquake. Stone masonry buildings in the old Quebec City were selected as an example due to their high vulnerability. The procedure determines the nonlinear behavior of buildings with capacity curves, and the probability of damage states with respective displacement fragility curves. These two inputs are convolved with the response spectra reflecting the local seismic settings. A series of earthquake scenarios were applied to estimate damage. The most damaging earthquake was with magnitude 7 and distance 20 km (M7R20), which generated about 18% probability of complete damage to stone masonry buildings. The obtained damage estimations were validated against empirical vulnerability functions based on damage data observed during past earthquakes.
Summary(Plain Language Summary, not published)
Many historic buildings in the old urban centers in Eastern Canada are made of stone masonry with un-measurable architectural and cultural heritage. These buildings generally offer poor resistance to lateral seismic loads. A rapid damage assessment procedure is proposed and validated with simulation of seismic vulnerability of stone masonry buildings in the Old Quebec City.
