Bridge structures are exposed to several chronic and abrupt stressors, among which the combined effects of corrosion and earthquakes pose a major threat to their long-term safety. Probabilistic risk assessment frameworks that quantify and propagate uncertainties inherent to these phenomena are necessary to mitigate this threat. This paper...

The paper presents a risk assessment model, developed in the project oVERFLOw and further implemented in the project CROSScade, for determining the direct and indirect impacts of flooding hazards. As a consequence of flooding, transport infrastructure and flood protection systems can be significantly damaged and cause cascading effects on other...

Due to climate change, the risk of flooding is increasing with potentially severe consequences on highly populated and economically developed coastal zones. Storm surge barriers protect against such events with the critical task of closing during extreme weather conditions to prohibit the propagation of water. This highlights the importance of...

Improvement in rail asset safety, comfortability and serviceability is gaining importance. This requires effective service life management by incorporating multi-stakeholder desires in the early design stage. Typical stakeholders are asset owners, train users and maintenance service providers. To allow for this change, the traditional single...

Next decades, many hydraulic structures in the Netherlands will reach their end of life. Timely mitigation requires accurate estimates of the end of life. This appears however hard since many external drivers and multiple functions may lead in many plausible combinations to insufficient technical or functional performance. As a consequence, a...

In the coming decades, the storm surge barriers in the Netherlands will reach their end of the designed life time of 100 years. Therefore, the Dutch storm surge barriers are preparing for major renovations. Next to this, as a result of the expected sea level rise, the hydraulic loads and the number of necessary closures will exceed the original...

Floating wind farms are a promising solution for offshore wind energy production in deep waters. However, the design optimisation process of these farms is difficult due to their complex and multidisciplinary nature. Furthermore, current optimisation methods: 1) ignore and/or provide no insight into the dynamic interplay between the preference...

The technical solutions for deconstruction are reviewed and investigated in the building sector as this is an expected trend under the sustainability requirements set in the EU Commission´s “Green Deal” towards net zero greenhouse gas emissions by 2050. Two of the main research areas for efficient deconstruction strategies are; i) the behavior...

The pumping-weir complex at IJmuiden plays an important role in the drainage of excess water in the Western Netherlands. Multiple pumps need replacing as 4 out of 6 pumps near their end-of-life term. The optimal replacement strategy critically hinges on the future required pumping capacity. Yet, currently available models are not suited to...

One of the methods for the assessment of existing bridges is to subject the bridge to a load test. What is still lacking is a reflection of these recent advances in the codes and guidelines used for load testing of bridges. Two approaches are being used to address this lack. The first approach attempts to answer fundamental questions with regard...

In the assessment of existing infrastructure performing only a desk study is often not sufficient to determine the structural reliability of a bridge or viaduct. For concrete structures gathering field data by performing a proof load test offers detailed information about the structural performance. However, the relation between the magnitude...

The present paper discusses the application principles of value of information theory in adaptive metamodeling for reliability analysis. Metamodeling for reliability purposes has become particularly relevant in recent years. The usage of metamodels allows surrogating the, costly to evaluate, performance functions of engineering structures....

Acoustic Emission (AE)-based crack tracking is a promising approach to locate cracks in concrete structures. Different from conventional AE, this approach uses AE activities during crack closure. But, AE activities during crack closure may be influenced by the number of load cycles and loading speed. This may challenge the applicability of AE...

Proof load testing can be an interesting method to assess existing bridges for which analytical methods are unable to provide an accurate assessment. In a proof load test, a load representative of the factored live load is applied to the bridge. If the bridge can carry this load without distress, the proof load test is success-ful, and the...

As the bridge stock in The Netherlands and Europe is ageing, various methods to analyse the capacity of existing bridges are being studied. Proof load testing is one of the method to test the capacity of bridges by applying loads on the existing concrete bridges with small spans. Because of the fact that neither the actual traffic load nor the...

For asset management of flood defences a pivotal aspect is the quality and accessibility of available data and information. In the management of flood defences inThe Netherlands, safety assessments are conducted every twelve years. To assure the quality and consistency of these safety assessments, flood defence engineers have to make use of a...

In The Netherlands, inspection and maintenance are essential for maintaining stringent flood protection standards. Flood defences are assessed every 12 years to ensure they meet their risk-based safety standards,which are given as legally-binding maximum failure probabilities. Between assessments, flood defence managers are subject to risk...

Life cycle performance and risk management are often mentioned as critical tasks for infrastructure managers. However, without proper data collection and analytics these tasks cannot be executed. This paper discusses lessons learned from a case where a data analytics approach was deployed when an unexpected phenomenon occurred on the Dutch...

General frameworks for reliability differentiation have evolved over time and are mainly developed for new buildings. However, recommendations for existing quay walls are lacking. In this study target reliability indices for assessing existing quay walls were derived by economic optimisation and by evaluating the Life Quality Index criterion ...

A proper allocation of risks and responsibilities is vital for the success of long-term maintenance contracts. This paper focuses on a method to identify an adequate allocation of responsibilities for the maintenance of waterworks. The Dutch agency recently started outsourcing the maintenance of their waterworks in DBFM contracts. In order to...
