Abstract

The core idea of the PBSD is the probabilistic assessment of the structural performances due to seismic action. Within this framework a central role is played by the so called PSDHA; the main shortcoming which prevent the effective application of such a approach currently lies in the large dispersion of the structural response (as evaluated through properly chosen DM or EDP) obtained from non-linear dynamic analysis which uses as input selected earthquake acceleration time histories. This paper, referring to a general procedure for the identification of representative groups of earthquake inputs proposed by the authors identifies a practical proposal for the effective application of the methodology based upon the use of a vector-valued IM composed of PGA and PGV, and proposes the use of “representative” EPI groups characterised by a (1) a vectorial IM composed of PGA and PGV and (2) a specific ratio of near-field records to far-field records.
