A new method to establish empirical fragility models is proposed.
- el">•
Post-earthquake damage observations are utilized to develop fragility curves.
- el">•
The uncertainty related to ground motion intensities at the damage observation sites is taken into account.
- el">•
This uncertainty is due to geospatial variability of ground motion intensities and the sparseness of strong motion networks.
- el">•
Fragility curves are developed for reinforced concrete buildings with limited ductility capacity.
