Scenario Earthquake for Spatially Distributed Structures

Abstract eng:
The catastrophic nature of seismic risk resides in the fact that a group of structures and infrastructure is simultaneously excited by spatially correlated seismic loads due to an earthquake: thus, both inter-event and intra-event correlations of ground motion measures must be taken into account. The spatial correlation of seismic demand affects aggregate seismic loss and identified scenario seismic events. In this study, a simulation-based seismic risk model for spatially distributed structures is developed. Analysis results indicate that adequate treatment of spatial correlation of seismic demand is essential in assessing the probability distribution of aggregate seismic loss, and that underestimation of spatial correlation of seismic demand leads to possible overestimation of scenario events.
