Session 2.2 GNGTS 2024 Fig. 3 - Fragility curves obtained for the four studied configuraCons (PGA) Conclusions In this work, four possible configuraCons of crustal and local structural models were analyzed to idenCfy their influence on the IM-EDP relaConship and, consequently, on fragility curves. In terms of demand, reflecCng the distribuCon of possible signal intensity measures, configuraCons where crustal model CR2 is present showed higher values. The influence on the intensity measure values of crustal models seems to be, in the analyzed cases, more significant than that of local models. Examining the IM-EDP relaConship and consequently the fragility curves, it is observed that the regressions performed on IM-EDP pairs do not overlap. This implies that the intensity measures analyzed are not sufficient even in the studied case, where a single scenario is represented. In parCcular, the dependence of these measures on local and crustal structural models has been highlighted.
