Abstract With reference to the issue of the evaluation of the purchase prices for leasehold properties, in Italy the transfer of properties built as part of regulated housing initiatives is restricted by a series of constraints, the removal of which entails a set of fees to be borne by the housing lessees. This study, starting from an analysis of similar tools applied in other European territorial contexts, provides a methodological approach for estimating these fees while simultaneously considering the framework established by the current regulations, the trends in the residential market, and the inflation dynamics.

Abstract Numerical time integration still constitutes a rather challenging task when applied to quite stiff structural systems, especially in the presence of complex vibration scenarios. In this context, the accurate evaluation of all displacement, velocity and acceleration dynamic response variables, specifically due to a Moving Load (ML) excitation, poses serious difficulties in possibly reconciling calculated and measured dynamic responses. The present work refers to a novel computational strategy allowing for an “exact” integration within the time-step, and benchmarks its outcomes for the comparison with the numerical integration by known methods. The analysis is exemplified on a continuous beam with multiple spans, including ML transit and subsequent window of free vibration response. The broader underlying framework is that of Structural Health Monitoring (SHM) of a historic railway bridge, which truly challenges the reliability of integration methods in correctly tracing the current dynamic response, in view of system identification and digital twin replication, toward informed management and maintenance scenarios.

Abstract The San Michele Bridge, also known as Paderno d’Adda Bridge, stands as a striking example of 19th-century iron architecture and a prominent symbol of Italian industrialarchaeology heritage. Constructed between 1887 and 1889 by the Societ`a Nazionale delle Officine di Savigliano (SNOS), this impressive infrastructure spans over the Adda River, linking the towns of Paderno d’Adda and Calusco d’Adda, near Milano. Since its inauguration in 1889, the bridge has continuously served as a vital connection between the provinces of Lecco and Bergamo in Lombardy, northern Italy. Following nearly 136 years of service, the bridge underwent extraordinary restoration works from 2018 to 2020, ensuring up to now its continued functionality for both railway and road traffic. After that, from May 7 to 10, 2024, a dedicated experimental campaign was conducted on the bridge to investigate its current structural response under various dynamic excitations, including ambient vibrations with no traffic, dynamic response with vehicular transit and controlled train passages. During such a campaign, diverse acceleration data were collected and then analyzed with the aim of extracting the salient modal properties of the bridge. A comparison of the processed data with available records prior to bridge restoration revealed a rather good correspondence with the identified modal properties, within a time span of about 14 years. This seems to suggest that the recent restoration works may have displayed a minimal impact on the global dynamic behavior of the structure, in terms of modal features. The findings from this study shall provide valuable insights for future research developments and contribute to the ongoing deployment of a Structural Health Monitoring (SHM) platform for the San Michele Bridge, contributing to the long-term goal of monitoring and preserving this historic viaduct.
