ABSTRACT
One of the main issues in the rehabilitation of old masonry buildings is the structural rehabilitation and the verification of the structural safety. In structural rehabilitation, certain aspects should be taken into account: namely, the architecture, the state of conservation, the existent structure and the historical values of the building. A linear analysis can be used for macro-modelling when referring to the masonry work (stone blocks and mortars) as a homogeneous and continuous material, unlike micro-modelling, in which the properties of the materials are distinguished and should be taken into account separately. This chapter presents the case study on a building located in the old historical city of Leiria, in Tenente Valadim street, adjacent to the river Lis. The analysis of the geometrical characteristics and the identification of the materials were performed by recording data for all the structural and nonstructural elements, and the results are summarized.
