DESIGN EARTHQUAKES AND SEISMIC DEMAND FOR PBEE IN FAR-FIELD AND NEAR-SOURCE CONDITIONS

The features of L'Aquila records were also compared to those of the NGA database to check whether they are in agreement to what expected for impulsive and non impulsive near-source records. The analyses include also rupture-rotated and vertical components of motion. Finally all the recent models regarding pulse-like effects (applied also in the analyses mentioned above) are used for a PSHA which is modified in order to account for near-source conditions (Iervolino and Cornell, 2008). Also disaggregation analysis is adapted to near source conditions as suggested by literatures (Thotong et al., 2007). Illustrative cases are analyzed: they can be considered as some of the first numerical applications of the most recent procedures and they are a way for identifying advantages and limits and for contributing to future improvements.
