The accurate modelling of seismic load is a major topic that has raised particular interest in the literature in the recent years. One of the reasons is the advent of performance based earthquake engineering (PBEE) that has become the state of the art for both civil and nuclear structures. The PBEE generally requires transient analysis in order to evaluate the seismic fragility of structures an...

Ground-motion prediction (attenuation) models predict the probability distributions of spectral acceleration values for a specified earthquake event. These models provide only marginal distributions, however; they do not specify correlations among spectral accelerations with differing periods or orientations. In this article a large number of strong ground motions are used to empirically estima...

This work presents a novel empirical Ground Motion prediction Model (GMM) for vertical-to-horizontal (VH) response spectral amplitudes up to 10 s, peak ground acceleration and velocity shallow crustal earthquakes in Italy. Being calibrated on the most up-to-date strong motion dataset Italian (ITA18), model is consistent with ITA18 GMM horizontal motion. property makes useful probabilistic seism...

Seismic risk assessment of new and existing structures has a long history, which is based on the development specific methods for seismic hazard vulnerability analyses. Performance-based earthquake engineering natural evolution integration all these aspects that nowadays implemented in several precodes. However, some critical are not yet completely clarified. As matter fact, analysis suffers so...

Probabilistic seismic hazard analysis [PSHA, e.g., Cornell (1968); Anderson and Trifunac (1978); McGuire (1977); McGuire (1995)], typically used in risk assessment and hazard mitigation, has so far relied on ground motion prediction equations (GMPEs), also called attenuation relations [e.g., the next generation attenuation relations or NGA by Campbell and Bozorgnia (2008); Chiou and Youngs (200...
