Resumo(s)
The preservation of the built heritage has long been a public concern, mainly due
to fears about the loss of identity, history and heritage of populations. The main
concerns are the conservation and restoration of monuments that usually represent
important events in the history of a city or a country. More recently, urban residents
and policymakers have become aware of the abandonment or degradation of old city cores, leading to mischaracterisation of the buildings and ways of living.
To preserve history and promote building and urban renewal, considering the
basic principles of the preservation process, it is important to introduce the least possible disturbance. To start with, the diagnostic process is a key aspect, especially to investigate the construction characteristics and the damage to materials, and to find structural and nonstructural problems.
To start any process, a visual inspection, a study and knowledge of the original
construction methods and materials and historical repair techniques can help but
may not be sufficient, and the use of conventional techniques to complement the
information needed can result in an insufficient understanding or in extensive and
unnecessary intrusions in the construction.
In recent years, the rapid growth of science and research, combined with the
industry and the need to gather more and accurate information, have led to the fast
development of nondestructive testing methodologies that allow the architectural
archaeology to be studied, the structural assessment to be supported and information to be given about the material properties. Each technique can be used for a specific purpose, but, in some cases, only a combination of techniques is reliable and gives an accurate interpretation of the data acquired.
The fundamental contribution and aim of this book is to give a full overview of several case studies where different nondestructive techniques have been applied, in several cases using multidisciplinary approaches, which aim to highlight the importance of the information acquired and encourage the use of these techniques in future studies.
The book brings together 16 chapters focused on nondestructive testing techniques
applied at the urban building level and also applied to monumental buildings,
archaeology and cultural heritage, bringing together more than 40 international
researchers and experts in the field, who are the source of practical case studies supported by a theoretical background.
