subsequent seismic events. This highlights the necessity of employing state-dependent fragility models that effectively account for the degradation of structural capacity over time. 6. Conclusion This study advances fragility assessment methodologies by presenting a comprehensive approach for deriving state-dependent fragility curves, emphasizing the influence of prior damage on the probability of exceeding various damage states. The proposed models produce both independent and dependent fragility curves that are logically ordered and tailored to reinforced concrete Italian building typologies. These curves provide a robust foundation for seismic risk assessment and can be effectively integrated into probabilistic seismic risk analysis frameworks. References Cornell, C.
