Abstract

It is nowadays recognized the importance that Cultural Heritage has as a testimony of cultural and historic identity. Thus the original constituent materials and structural forms need respect both in view of transmission of their true values to future generations and in view of valorization of this reach heritage. Nonetheless historic structures are subjected in their lifetime to a series of modifications and aggressions, mainly due to their environment [1]. Due to the fact that some types of damage can affect the life expectance of the structure, it is required that the acquisitions of structural, material and environmental parameters by monitoring systems be complete and reliable in order for the damage and its evolution to be detected. To reach this goal, a great amount of research and applied work is still needed. In the European research project SMooHS dedicated to smart monitoring of historical constructions, great attention is devoted to enhance current capabilities of experimental diagnosis of structural and material deterioration affecting historic structures due to environment; in addition to improve presently available monitoring systems and to validate the reliability of data acquired via long-term monitoring sensors [2]. Laboratory and site tests, by employing a combination of both lab analyses on samples and state-of-the-art non-destructive diagnostic techniques have been applied to on-purpose-built lab specimens (brick and stone masonry and their components, timber) as well as to real case study buildings. Comparison of experimental data has been performed in order to achieve a major advancement on current diagnostic procedures and a sure condition evaluation of the structure, with regard for example to moisture, salt content and presence of crack patterns in masonry [3]. This contribution would like to provide an overview on the work carried out and on the main presently available achieved results from the measurement campaigns. The tasks have been accomplished by combination of testing techniques (from non destructive to destructive) for investigating variations of physical, geometrical and mechanical parameters affecting material deterioration and evolution of structural damage.
