WBI2017 Code Calibration : reliability-based code calibration and semi-probabilistic assessment rules for the WBI2017
Publicatie type | monografie
The primary flood defenses in the Netherlands have to comply with the flood protection standards from the Water Act. These were updated in January 2017. Because of this change in the type of standard, a new set of tools and guidelines had to be developed for assessing the safety of primary flood defenses : the WBI2017 (Wettelijk Beoordelings Instrumentarium ). For reasons of consistency, efficiency and transparency, a standardized code calibration procedure was developed. This report provides an overview of this procedure and discusses its application to the following failure mechanisms: 1. internal erosion (uplift, heave and piping), 2. slope instability (macro instability), 3. dune erosion, 4. block revetment failure caused by wave impacts, 5. asphalt revetment failure caused by wave impacts, 6. grass revetment failure caused by wave impacts, 7. grass revetment failure caused by wave run-up. The report summarizes the results of studies carried out by various researchers.
