A Current

The assessment of the seismic safety level of masonry buildings is a current and important issue at the basis of the complex process of preservation of historical masonry buildings which constitute mostly the Italian and European towns. Nowadays, different approaches able to provide important information concerning the seismic safety level of masonry structures are available. Among these, fragility curves allow to have a prediction of potential damages during an earthquake of geographical areas characterized by similar construction typologies. The present paper concerns the derivation of fragility curves of masonry buildings, typical of Italian historical towns and mainly characterized by the possible occurrence of local out-of-plane collapse mechanisms. To this end, a real case is accounted in the study in order to consider specific parameters characterizing the constructions composing these territorial realities.

Historic masonry buildings experience a high seismic vulnerability: innovative intervention strategies for strengthening, based on the use of fibre-based composite materials are gradually spreading. In particular, the coupling of fibre-based materials with mortar layers (Fibre Reinforced Mortar technique - FRM) evidenced a good chemical and mechanical compatibility with the historical masonry and proved to be effective for the enhancement of both in-plane and out-of-plane performances of masonry, contrasting the opening of cracks and improving both resistance and ductility. The resistant mechanisms that arise in FRM strengthened masonry walls subjected to in-plane horizontal actions are analyzed in the paper and a practical design approach to evaluate their performances is illustrated, evidencing the dominant collapse mode at the varying of the masonry characteristics. Some masonry walls are analyzed numerically and analytically, as “case study”.

Historical Masonry

The structural safety evaluation of monumental and historical buildings in seismic prone areas requires the availability of appropriate verification tools, in order to ensure both a realistic estimation and the feasibility of the method. In the case of historical masonry structures, such as palaces or churches, local damage mechanisms often take place (e.g., out-of-plane overturning). A procedure to assess the seismic vulnerability of these mechanisms, focusing on the damage limitation state, is developed through equilibrium limit analysis. Moreover, the possibility of enriching the formulation, including constructive and technological aspects, which may modify structural response, is shown.

AbstractA hybrid seismic fragility model for territorial-scale seismic vulnerability assessment of masonry buildings is developed and presented in this paper. The method combines expert-judgment and mechanical approaches to derive typological fragility curves for Italian residential masonry building stock. The first classifies Italian masonry buildings in five different typological classes as function of age of construction, structural typology, and seismic behaviour and damaging of buildings observed following the most severe earthquakes occurred in Italy. The second, based on numerical analyses results conducted on building prototypes, provides all the parameters necessary for developing fragility functions. Peak-Ground Acceleration (PGA) at Ultimate Limit State attainable by each building’s class has been chosen as an Intensity Measure to represent fragility curves: three types of curve have been developed, each referred to mean, maximum and minimum value of PGAs defined for each building class. To represent the expected damage scenario for increasing earthquake intensities, a correlation between PGAs and Mercalli-Cancani-Sieber macroseismic intensity scale has been used and the corresponding fragility curves developed. Results show that the proposed building’s classes are representative of the Italian masonry building stock and that fragility curves are effective for predicting both seismic vulnerability and expected damage scenarios for seismic-prone areas. Finally, the fragility curves have been compared with empirical curves obtained through a macroseismic approach on Italian masonry buildings available in literature, underlining the differences between the methods.
