Seismic Assessment and Retrofit of Historical Masonry Structures

Particular attention was also paid to the comparison between the “as built” panels and the strengthened ones by means of failure modes and crack patterns. Therefore, the present work was arranged in order to specify the structural typology where the introduced strengthening system could be applied, describing the different masonry structures and their main performances under seismic actions, such as shear capacity and failure mode. The work goes on describing the characterization of materials used in the simulation phase, the model by using DIANA software [5] considering both “as built” and strengthened masonry panels, the comparison between the numerical analyses results and experimental ones in order to validate the modelling and, at the end, to implement the parametric analysis by changing the geometrical and mechanical properties.
