A theoretical‐experimental approach for assessing the vibration impact due to vehicular traffic upon the heritage building structures

Abstract

In past years, a new method of structural analysis has been developed for assessing the vibration impact due to vehicular traffic upon the heritage building structures. This method is based on on the conjuncture among the monitoring of the structure, and the structural identification. The satisfaction of such demands in the case of buildings already realized, above all if ancient, can be prevented by the impossibility to reach to a complete knowledge both of the structural organism and the strength state of maintenance of every component of the building. An exhaustive knowledge would be achievable only applying such methods of investigation to induce heavy troubles to the analyzed manufactured article. From these consideration the idea of the construction of an elementary system is born. An elementary PC model, that is an ideal receiver whose all the mechanical and geometric characteristics are known, has been designed for in situ analysis and excited applying the experimental vibrational levels in order to evaluate the response. A further development is to realize the physical model and execute local experimental campaigns. This operative system has to be transportable and positionable near the source without holding up the traffic nor damaging the measurement site.
