As paredes de tabique, uma técnica de construção tradicional, encontram-se em todo o
território português, com maior incidência no norte. Verifica-se uma pronunciada
variabilidade de materiais empregues, das dimensões e dos detalhes construtivos. A
reconhecida necessidade atual de reabilitar este património edificado justifica a investigação
desta técnica construtiva de modo a definir com rigor as intervenções de reabilitação.
Foi desenvolvido um estudo relativo às construções no centro histórico de Viseu, onde as
paredes de tabique surgem como elementos de compartimentação, como elementos de
fachada ou como elementos principais da estrutura. Após a seleção de amostras
representativas de paredes de tabique, foram estudados os seus elementos constituintes,
nomeadamente a madeira, as argamassas e os elementos de ligação. Procedeu-se a uma
análise experimental das mesmas, de modo a conhecer e caracterizar as suas propriedades
mecânicas. Posteriormente foram realizados ensaios de flexão em paredes de tabique à escala
real. Tendo por base os resultados obtidos, propõe-se o desenvolvimento de um modelo
numérico que seja capaz de simular o seu comportamento estrutural, permitindo a sua correta
incorporação na modelação estrutural dos edifícios antigos. Conclui-se a importância destas
construções tradicionais no comportamento global das estruturas.
ABSTRACT: “Tabique” walls, a technique of traditional construction, can be found along the Portuguese territory with the highest incidence in the north. There is a marked variability in materials used, dimensions and construction details. The recognized current need to rehabilitate this heritage structure type justifies the investigation of this construction technique to define accurately the rehabilitation interventions. A study was conducted on the buildings in the historic centre of Viseu, where “tabique” walls appear as elements of compartmentalization, as façade elements or as main structural elements. After the selection of representative samples of “tabique” walls, we studied its constituent elements, namely wood, mortar and the connecting elements. Afterwards, an experimental analysis was performed in order to know and characterize the mechanical properties of these walls. Posteriorly were conducted bending test the "tabique" walls to real scale. Based on these results, the development of a numerical model was made and proposed, which is able to simulate the structural behaviour, allowing its correct incorporation into structural modelling of old buildings. We conclude the importance of this traditional technique in the overall behaviour of the structures.
