Assessing the seismic vulnerability of masonry buildings - Seismic Risk Analysis and Management of Civil Infrastructure Systems - page 355

The application of the FaMIVE procedure to a number of cases in regions
of different seismicity shows the relevance of construction details and the
importance of considering the different failure mechanisms separately to
identify realistic risks of failure. The comparison of the computed average
drift for each case with the code prescription and the experimental evidence
shows that the code prescription underestimates drift for in-plane behav-
iour, while there is reasonable agreement for the out-of-plane, especially
for the near collapse limit state. A procedure for the computation of the
performance point given performance criteria and hazard return period is
introduced to show the variability of performance points for different
failure behaviour and how they affect probability of failure computed as
average. The random uncertainty associated with this type of analysis is
presented in terms of fragility curves that can be modelled as the lognormal
distribution. In the same way, the epistemic uncertainty associated with the
modelling procedure is also evaluated using the same approach. Results
show that the epistemic uncertainty accounts for approximately 11% varia-
tion in results, while comparing results for different locations and failure
mechanisms show much greater variability.
