Seismic Assessment of a Masonry Bridge: Analysis and Retrofit

This paper presents a comprehensive study of an ancient masonry arch bridge, including structural verification, condition assessment, and proposed enhancements. The research involves a detailed survey using LiDAR and aerial techniques, mechanical inspections, development of a structural model, and rigorous verification of its seismic response and safety compliance. The study proposes structural improvements targeting identified vulnerabilities and evaluates their feasibility according to the Italian and European Standard Regulations. Comparisons between different retrofitting techniques are discussed, contributing valuable knowledge to masonry arch bridge rehabilitation.
