Resumo

We analyse the impact on the reliability estimation of multi-span beam continuous structures when data about the displacement of the points contained in a small region is considered. The reliability is estimated by using inverse problems techniques combined with a Bayesian method. Some numerical experiments are performed to obtain conclusions concerning the influence of the extension both in time and space for the displacement field observation, as well as the influence of the distance between measurements and crack location on the reliability estimation.
