Seismic risk of R.C. building classes

摘要: Seismic risk assessment on a large scale may be defined as the prediction of fraction buildings expected to reach conventional limit state in region and time period interest. This definition is frequentistic interpretation failure probability for homogeneous class structures. Empirical post-event survey methods vulnerability evaluation not fit purpose seismic analysis at level pure analytical approach required. To this aim paper proposes extension structure-specific reliability procedures, but without assuming single structure representative class. The class-capacity function approximated by regression significant cases analyzed Static Push-Over (SPO); demand obtained Probabilistic Hazard Analysis (PSHA). computed simulation former being exceeded latter via Capacity Spectrum Method (CSM). Explanatory application refers six classes Italian rectangular R.C. buildings; three are pre-code constructions, designed only gravity loads, whereas other considered with old codes accounting capacity design rules. c 2006 Elsevier Ltd.
