Probabilistic risk assessment of RC building structures with masonry infills

Abstract

The study of the seismic vulnerability of existent buildings in urban areas with moderated/high seismic risk is of extreme importance. Earthquake engineering experts, public authorities and general public alike agree on the idea that the assessment of the seismic safety and performance of the built environment is a matter of high priority.The proposed paper aims to carry out a structural fragility study where a representative RC building structure is modelled considering different characteristics (without masonry infills, with masonry infills and considering different mechanical characteristics of the infills). As the definition of fragility curves for the different analysis cases is the main objective of the study, the general outcome of the study will enable to assess the global importance of the referred material and mechanical uncertainties in the final fragility values and, therefore, in the potential mitigation measures that will be based on such results.
