Abstract (EN):
A probabilistic methodology is proposed for the seismic performance analysis of existing buildings
using global metrics to determine if the behavior conforms to a given limit state. The referred performance
metrics are the mean annual frequency of the limit state, the corresponding expected loss
associated to the repair of the building, and the corresponding number and type of mechanisms that
occur. The consideration of these assessment parameters to control building performance widens
the scope of the limit state definitions proposed in current codes. Therefore, current limit state
descriptions were updated to establish adequate risk- and cost-related limit state definitions using
the Eurocode 8 Part 3 proposals as a basis for discussion. The description of the proposed procedure
is detailed and addresses its applicability for different limit states and its ability to include the uncertainty
in the limit state capacities. An application involving the performance analysis of a reinforced
concrete structure for several limit states is also presented and discussed.
