| Abstract: | In this study, we address the effective method to apply a novel reliability method integrated with finite element models to
the safety assessment of pilot site Scheldt in the Netherlands. This site was considered as one of the three main pilot sites
in Europe to assess the application of newly suggested techniques in order to reduce and manage the flood risk in the Floodsite
project. , 2004–2009). The novel method of dynamic bounds (DB) is applied to this site after a successful experience in (Rajabalinejad in Reliability
methods for finite element models, 1 edn. IOS Press, Amsterdam, 2009). In this study, the bi-functional response of the finite element model is considered, and the dimensional uncertainty is
defined presenting the expected uncertainty for a certain dimension in the DB method. The uncertainty is used as a judgment
tool to choose the dimension for the DB method for the desired accuracy. The results obtained by applying this technique are
presented in this paper. |
