Fragility curves for RC frames under multiple earthquakes

This study aims to overcome previous limitations and derive fragility curves for three RC (reinforced concrete) buildings with different number of stories under multiple earthquakes. As-recorded seismic sequences in different regions around the world are employed and fiber-based modeling approach that captures degradation in concrete and reinforcing steel materials is used. The results indicate that considering damage from previous events, number of stories, and earthquake region significantly affect fragility curves.
