Typology based methodology for in situ testing of masonry

Detalhes bibliográficos
Resumo:Masonry and stone masonry in particular, has been the main building material throughout history in vast parts of the world. This extremely rich and variable material has a unique and not completely comprehendible nature, both in spatial-architectural terms and from the engineering point of view. The knowledge of material properties of historic masonry is often lacking, and furthermore, even when material properties are available, the constitutive laws coming from a good knowledge of the material are not enough. Many academic and practical efforts have been made offering different approaches to classify historic masonry, striving to unfold its complexity and to cast logic into its diagnostic approach. The aim of this thesis is to contribute to the gained knowledge of historic masonry in Portugal and its diagnosis procedures. The main objective is to propose practical methodologies for diagnosis of historic masonry structures, corresponding to their typological characteristics. The study is based on the Portuguese architectural landscape, yet has global classifications, and thus can be useful for any diagnosis procedure of a historic masonry wall. In order to develop such methodologies, information relating to historic masonry typologies in Portugal is gathered and classified. Consecutively, techniques for assessment of historic masonry are studied, and all information is integrated and utilized to develop typology oriented diagnosis procedures. These procedures are classified into rural, urban and military building types, and offer general guidelines for diagnosis of such structures, as well as in depth suggestions for specific diagnosis procedures. In addition, the recommended methodology is tested and validated in a diagnosis campaign carried out in the Guimarães Castle. The development process illustrates that many advantages can be drawn to the field of historic heritage diagnosis by utilizing typological information. By considering both physical (geometry, morphology, etc.) and theoretical aspects of the typologies, different approaches to their diagnosis arouse. The validation process highlights the importance and value of precise pre-planning of the diagnosis procedure on one hand, but finds the necessity of flexibility in the on-site campaign on the other. In order to employ this approach in practical campaigns, further study and classification must be attained. Yet hopefully this work can take us one step closer to decipher the comprehension of historic masonry.
