Mainshock-Integrated Aftershock Vulnerability Assessment of Bridge Structures
Seismic fragility analysis is often conducted to quantify the vulnerability of civil structures under earthquake excitation. In recent years, besides mainshocks, strong aftershocks have been often witnessed to induce structural damage to engineered ...

Influences of site conditions and ground-motion frequency characteristics on structural fragility
Site conditions and ground-motion frequency characteristics play a significant role in structural response and seismic damage distribution. However, the current structure fragility analysis techniques have hardly considered such effects. Taking the ratio

Influence of ground motion duration on seismic fragility of base isolated NPP structures
This study investigates the influence of earthquake duration on seismic fragility of base isolated nuclear power plant (NPP) structures. Two groups of ground motions are employed in performing time history analyses, in which short duration (SD) and long ...
