Acknowledgements The authors gratefully acknowledge funding from the Italian Ministry of University and Research through the PRIN Project “ TIMING ” – Time evolution laws for IMproving the structural reliability evaluation of existING post tensioned concrete deck bridges” (protocol no. P20223Y947). The work has been also supported by FABRE - research consortium for the evaluation and monitoring of bridges, viaducts and other structures through the project ”SAFOTEB - a reviewed safety format for structural reliability assessment of post-tensioned concrete bridges. The authors wish to extend their heartfelt appreciation to Centro Sperimentale Stradale ANAS for generously sharing the outcomes of the field tests conducted on the post-tensioning system.
