Effect of Uncertainties on Seismic Response of Steel Moment-Resisting Frames Affected by Sequence of Mainshock-Aftershock Earthquakes

The inherent uncertainties in the structural capacity and earthquake demand can significantly influence the performance of the structures under mainshock-aftershock sequences. In this regard, fragility models are robust tools for calculating cumulative damages considering uncertain parameters in both demand and capacity. However, some uncertain parameters need to be examined together to determine how they might affect the fragility analysis of …
