ABSTRACTModern societies understand built cultural heritage as a landmark of culture and diversity. Only during the last decades the idea that ancient buildings could be conserved and reused became appealing. Still, a large part of this heritage is affected by structural problems which menace the safety of buildings and people. The developments in the areas of inspection, non-destructive testing, monitoring and structural analysis of historical constructions, together with recent guidelines for reuse and conservation, allow for safer, economical and more adequate remedial measures. The paper addresses the issues of the methodology to adopt, of different cases studies and of present challenges. In particular, recent interventions in Portuguese cases studies (the Cathedral of Porto and a theological school in Braga) are analyzed in detail.Keywords: Cultural heritage buildings; Conservation and rehabilitation; Earthquakes and seismic engineering; Case studies.RESUMENLas sociedades modernas entienden su patrimonio cultural como un hito de cultura y diversidad. Sólo durante las últimas décadas la idea de que edificios antiguos podrían ser conservados y reutilizados se ha convertido en atractiva. Sin embargo, una gran parte de este patrimonio es afectado por problemas estructurales lo cual amenaza la seguridad de los edificios y personas. Los desarrollos en el área de inspección, ensayos no destructivos, seguimiento y análisis estructural de construcciones históricas, bien como recientes normas para reutilización y conservación, permiten medidas correctivas más seguras, económicas y adecuadas. El artículo aborda las metodologías adoptadas, en diferentes casos de estudio así como presentes desafíos. En particular, intervenciones recientes en casos de estudio en Portugal (Catedral de Porto y Seminario de Braga) son analizadas con detalle.Palabras Clave: Edificios de patrimonio cultural; Conservación y rehabilitación; Terremotos e ingeniería sísmica; Casos de estudio.

The article deals with the conservation of cultural heritage objects due to their potential widespread deterioration. The suggestion to solve this problem is to create an integrated system for complex monitoring of cultural heritage objects technical condition. The stages of creating a realtime monitoring system with the choice of non-destructive testing methods, the necessary instruments, and tools, the result of which is the formation of a decision-making mechanism for a particular object, are proposed. Conducting monitoring by means of modeling allows predicting the behavior of structures and the building as a whole, taking into account the implementation of restoration measures.

Non-destructive testing of objects and structures is a valuable tool, especially in cultural heritage where the preservation of the inspected sample is of vital importance. In this paper, a decorative marquetry sample is inspected with three non-destructive testing (NDT) techniques: air-coupled ultrasound, X-ray micro-tomography, and infrared thermography. Results from the three techniques were compared and discussed. X-ray micro-tomography presented the most detailed results. On the other hand, infrared thermography provided interesting results with the advantage of being cheap and easy in the deployment of the NDT method.

The infrared thermography has been developed for Non-Destructive Testing (NDT), stress analysis, and in the last 10 years for metal fatigue assessment. The present research enables to realize these different research objectives all together thanks to an innovative experimental procedure, which includes NDT by lock-in thermography, thermoelastic stress analysis, and fatigue parameters assessment by Rapid Thermographic Method ( RTM). The developed procedure has been performed on a set of hole-notched specimens, achieving good results and predictions in a relatively short time. Moreover, the fatigue strength reduction coefficients of the specimens were determined by RTM. This thermography-based approach is dedicated for structural analysis and fatigue evaluation; it is an interesting attempt to apply different thermographic methods to a common research topic.
