| dc.description.abstract | The paper details two monitoring systems implemented in the main nave of Santa Maria of Belém Church of the Monastery of Jerónimos, 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. INTRODUCTION Architectural heritage is a key issue to modern societies due to both cultural and economical aspects. Besides the historical aspect, tourism and leisure will be a major industry in the 3rd millennium and the existence of a monument or a monumental compound is often a key attraction of cities and countries. In the process of preservation of ancient masonry structures, damage evaluation and monitoring procedures are particularly attractive, due to the modern context of minimum repair and observational methods, with iterative and step-by-step approaches. High-priority issues related to damage assessment and monitoring are global non-contact inspection techniques, improved sensor technology, data management, diagnostics (decision making and simulation), improved global dynamic (modal) analysis, self-diagnosing / self-healing materials and improved prediction of early degradation. The present paper aims at several of the referred issues and is focused in the structural observation of a Portuguese monument: the Santa Maria of Belém Church of the Monastery of Jerónimos, in Lisbon. In the main nave of the church two monitoring structural systems were recently installed in order to understand the static and dynamic structural behaviour with the purpose of damage detection and the improvement of seismic resistance of the monument. Preliminary investigations, numerical non-linear analysis and the first dynamic modal identification analysis are described. Also the preliminary works for the monitoring systems are presented, including the selected points for observation, the discussion of the technical characteristics of the sensors, as well as preliminary inspection and diagnosis. The first results of the dynamic monitoring system are shown and the future developments on the two systems are presented. GENERAL DESCRIPTION OF THE MONUMENT The Monastery of Jerónimos is, probably, the crown asset of Portuguese architectural heritage dating from the 16th century. The monumental compound has considerable dimensions in plan, more than 300×50 m2, and an average height of 20 m (50 m in the towers). The monastery evolves around two courts. The construction resisted well to the earthquake of November 1, 1755. Later, in December 1756, a new earthquake caused the collapse of one column of the church that supported the vaults of the nave, which resulted in the partial ruin of the nave. In this occasion also the vault of the high choir | por |
