Abstract
All decisions that concern the development and
management of existent infrastructure are of extremely
importance for society. However, it is verified that these
decisions are influenced by a huge source of
uncertainties that must be taken into account. A
methodology that consider this, and, which objective, is
to support such decisions, is developed within this
research. In order to support such methodology, a
numerical model is developed. Such model is then
calibrated using backanalysis procedures, so that, given
results, could best fit obtained experimental data. The
developed model is continuously updated with collected
data, by using inference processes. Then, a full
probabilistic analysis is performed in order to evaluate
the respective structure behavior. This paper describes
such methodology, and the respective application with a
batch of reinforced concrete beams, tested at laboratory,
till failure. The developed methodology is applied with
success and obtained results revealed the respective
importance in future decisions concerning the societal
infrastructure. Further steps consider the application of
such methodology with a real structure.Fundação para a Ciência e a Tecnologia (FCT
