The paper presents the technical causes of the collapse of Annone overpass, which occurred in October 2016. The tests carried out to identify the characteristics of the materials used for the construction, the verification calculations that led to the identification of the critical mechanism in the collapse and the test on the structural element deemed critical at the time of collapse are summarized. The paper highlights the critical issues occurring concurrently with the passage of the exceptional transports, the safety coefficient in relation to the project loads at the time of construction and that at the time of the passage of the exceptional convoy. The note also highlights some critical aspects of the national infrastructural system, with particular reference to exceptional transports and the methods that could be used to prevent future accidents in the absence of macro-design mistakes.

Abstract

The paper presents the technical causes of the collapse of Annone overpass, which occurred in October 2016. The tests carried out to identify the characteristics of the materials used for the construction, the verification calculations that led to the identification of the critical mechanism in the collapse and the test on the structural element deemed critical at the time of collapse are summarized. The paper highlights the critical issues occurring concurrently with the passage of the exceptional transports, the safety coefficient in relation to the project loads at the time of construction and that at the time of the passage of the exceptional convoy. The note also highlights some critical aspects of the national infrastructural system, with particular reference to exceptional transports and the methods that could be used to prevent future accidents in the absence of macro-design mistakes.
