Explicit collapse analysis of bridges still represents an open challenge in numerical modeling. In this work, an innovative micro-modeling approach, the Applied Element Method, is used to investigate potential triggering factors that might have contributed to the collapse of the Morandi bridge (Genoa, Italy) that occurred on August 2018. To this end, the influence of several parameters, including reduction of cables cross-section (potentially induced by corrosion) and impulsive loading effects, has been scrutinized through a sensitivity study. Observed and pre-dicted debris were also compared to assess which of the various causative scenarios may be deemed as potentially plausible, and which may instead be readily excluded.

Abstract
Explicit collapse analysis of bridges still represents an open challenge in numerical modeling. In this work, an innovative micro-modeling approach, the Applied Element Method, is used to investigate potential triggering factors that might have contributed to the collapse of the Morandi bridge (Genoa, Italy) that occurred on August 2018. To this end, the influence of several parameters, including reduction of cables cross-section (potentially induced by corrosion) and impulsive loading effects, has been scrutinized through a sensitivity study. Observed and pre-dicted debris were also compared to assess which of the various causative scenarios may be deemed as potentially plausible, and which may instead be readily excluded.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
