The research project of the ‘’Mechanical characterisation of masonry walls and vaults in a modernist building in Barcelona’’ is aimed to validate the criteria for the evaluation and the assessment of the mechanical characterization of masonry elements of the building of Escola Industrial. The first purpose is to understand deeply the behaviour of masonry under compression and the methods to characterize its mechanical parameters that forementioned throughout a comprehensive bibliographical research. Innovative experimental destructive tests are calibrated and carried out in the Laboratory of Structural Technology of the Technical University of Catalonia (UPC – BarcelonaTech) and minor destructive techniques are implemented in situ in order to investigate the compressive behaviour of the masonry. For the minor destructive techniques, Windsor Pin Penetrometer test, Screw Helix Pull-out test and Torque Penetrometric test are carried out in situ to preliminarly evaluate the parameters and the compressive strength of the masonry. For the destructive techniques, compressive tests are implemented in brick, tile, stone and mortar specimens and the evaluation of Young’s modulus and Poisson’s ratio is carried out on brick specimens. The double punch test is investigated on the mortar joints along with the numerical analysis and the verification of the test with an objective to evaluate which parameters influence the assessment of the test and provide a novel contribution to the field as it has never been analysed before. Extraction of core cylinders is a beneficial method since it slightly damages the structure and it is executed both for brick and stone masonry. The extracted cylinders were subjected to compression tests in the laboratory according to the guidelines of UIC 778-3R formed by International Union Railways in order to provide insight on the behaviour and properties of the masonry. A general objective of this study is to encourage future research on these moderate destructive techniques of testing existing masonry, to facilitate the function on the minor destructive techniques on real existing structures in situ, enhance the development of current standards and provide a novel contribution to the field by implementing a completely new numerical study.
