摘要
In this presentation, we provide some of our research results focused on seismic hazard and risk modeling. We emphasize the characterization of ground motion measures, spatial incoherency model of multi-component ground motions, and estimation of seismic risk for a portfolio of buildings. We compared the seismic hazard estimated directly using directly data based approach and seismicity (source, occurrence and attenuation relation) based approach. We showed that the (average) lagged coherency for record components oriented along the principal axes is similar in magnitude to that for randomly oriented orthogonal horizontal components, and that the spatial correlation can important to calculate the seismic loss for a portfolio of building.
