| Abstract | ||
| This work deals with structural analysis and health monitoring (SHM) of a valuable structure of the twentiethcentury cultural heritage: the Flaminio Stadium in Rome. The Flaminio is one of the iconic reinforced concrete sport facilities designed and built by Pier Luigi Nervi for the 1960 Olympic Games of Rome. In view of the foreseen SHM activity, the structural analysis of the Flaminio Stadium is firstly reported by presenting either preliminary analyses, aimed at studying the stadium response under different modeling hypotheses, and a three-dimensional Finite Element (FE) model of the entire structure. It turns out that the main grandstand canopy plays a pivotal role in the Flaminio's structural response to seismic excitation; in addition, its state of conservation raises some concern. Therefore, the structural modeling and dynamic characterization of the canopy is deepened in the paper. Its unusual features, such as geometry, material characteristics and dynamic interplay with the hosting main reinforced concrete frames are thoroughly assessed. To validate the FE results, characterized by a high modal density, and investigate the response of the structure, dynamic tests carried out under operating conditions are presented. The output-only collected data are used to calibrate the initial FE model. The predicted static and dynamic responses of the canopy are eventually exploited to guide the design of a tailored monitoring system. The relevant data management is framed in a heritage building information modeling (HBIM) context. This study draws a viable process for a proactive structural conservation strategy of twentieth-century heritage buildings and infrastructures. | ||
