The cumulative damage from repeated shocks affects the building vulnerability to subsequent events. This paper introduces a methodology for estimating the displacement demand, assumed as a damage measure, to existing unreinforced masonry buildings during earthquake sequences in probabilistic terms, only given the intensity levels of each event of the sequence. The damage prediction is based on statistical interpretation of a collection of analytical results derived prior to the occurrence of the seismic sequence. This procedure can be a useful tool when a rapid evaluation of damage is desirable during the earthquake sequence, in order to be incorporated into risk and loss assessment calculations. The analytical results used for damage predictions consist of results of nonlinear dynamic analyses with a large number of unscaled records and a set of SDOF models representing undamaged and damaged URM buildings. In order to investigate the parameters that affect cumulative damage evaluation, application examples are developed by considering records from the Canterbury (New Zealand, 2010-2011) and the Emilia (Italy, 2012) earthquake sequences.
