Abstract(s)
This paper is part of a broader study under development at LNEC with the main aim of
defining general policies for the cost-effective seismic retrofitting of the existing
Portuguese building stock.
The paper will summarise the methodology implemented for determining accurate
capacity and fragility curves of existing pre-seismic design code reinforced concrete
(RC) buildings when subjected to seismic action. The methodology involved the
definition of probabilistic models of relevant input variables (geometry and materials),
performing advanced numerical models of RC buildings under seismic action, setting of
appropriate limit states and finally analysis of the results in order to derive the updated
curves for Portuguese building stock.
This paper will also present a comparison between curves obtained from the current
study and the corresponding curves currently being used in LNEC’s seismic risk
assessment platform (LNECloss).
