The aim of this work is to evaluate the structural reliability of a corroded dapped-end beam belonging to an existing 70-year-old reinforced concrete bridge, by comparing the results obtained from a semi-probabilistic method with those provided by a fully probabilistic approach using Monte Carlo simula-tions. The resistance of the element was evaluated through a strut-and-tie model where corrosion was applied, considering both the initiation and propagation periods. The study highlights the potential of semi-probabilistic analyses while recognising the superior accuracy of full-probabilistic methods.

Abstract
The aim of this work is to evaluate the structural reliability of a corroded dapped-end beam belonging to an existing 70-year-old reinforced concrete bridge, by comparing the results obtained from a semi-probabilistic method with those provided by a fully probabilistic approach using Monte Carlo simula-tions. The resistance of the element was evaluated through a strut-and-tie model where corrosion was applied, considering both the initiation and propagation periods. The study highlights the potential of semi-probabilistic analyses while recognising the superior accuracy of full-probabilistic methods.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
