Structural monitoring of the Monastery of Jerónimos

The paper details two monitoring systems implemented in the main nave of Santa Maria of Belem Church of the Monastery of Jeronimos, in Lisbon. The monitoring systems were installed to better understand the static and dynamic behavior of the structure, aiming at the damage detection and the improvement of seismic resistance of the monument. Preliminary investigations, numerical non-linear analyses and the first dynamic modal identification analyses are described in the paper. Also the preliminary works for the monitoring systems are presented, including the points selected for observation, discussion of the sensors technical characteristics, as well as preliminary inspection and diagnosis. The first results of the dynamic monitoring system are shown and the future developments on the systems are presented, aiming at a full integration of all the adopted techniques.
