Reliability-Based Partial Factors Considering Spatial Variability of Strength Parameters

The stability of six regional dyke cross-sections in the Netherlands was re-assessed using the random finite element method (RFEM), which explicitly accounts for the spatial variability of strength parameters. The RFEM assessments of the cross-sections were shown to result in significantly narrower response distributions than those obtained...

The history of safety factors for Dutch regional dykes

Regular dyke assessment is part of reducing the risk of flooding in the Netherlands. 18 000 km of dykes are assessed at regular intervals, of which 14 000 km are classified as regional dykes and their main aim is to defend polders from inundating. The methods of assessing regional dykes are strongly inter-twined with the methods of assessing...

Calibration of Partial Factors for Basal Reinforced Piled Embankments

In the Netherlands, the design guideline for basal reinforced piled embankments has been revised (CUR226:2015) adopting a new analytical design model (The Concentric Arches (CA) model, Van Eekelen et al., 2013; 2015). The CA model provides geosynthetic reinforcement (GR) strains which were compared with laboratory and in situ measurements (Van...

Comparison of Methods for Reliability Calibration of Partial Resistance Factors for Pile Foundations

Uncertainties are a hall mark of engineering design leading to the development of risk and reliability informed basis for decision making. Accordingly three different but related levels of approach, namely a risk based, a reliability based and a semi-probabilistic approach have been proposed in ISO 2394. However, for code development the semi...
