A seven-story isolated unreinforced masonry building is used as a case study. The typology to which the studied building corresponds is characterized by unidirectional iron beams-brick vaults slabs, supported by a system of solid clay brick load-bearing walls. Concerning the probabilistic assessment, the compressive strength (f m ), Young modulus (E), shear modulus (G) and shear strength (τ 0 ) of the solid clay masonry were considered as random variables. The damage assessment of the structure is inferred from the results obtained using the incremental dynamic analysis approach, which estimates the response of the structure when subjected to different levels of demand (pga) and a set of different ground motion records previously selected through the conditional spectrum method. The simple random sampling method without replacement was applied in order to obtain sufficiently representative samples for both, the values of the mechanical properties to be used, and the number of dynamic analyses to be performed. The results are categorized in accordance to the variables of interest. The response of the structure presents a visible tendency of higher values for the control variable, δ roof , as the f m values decrease and the pga values increase.
