High ductility steels for impact resistance: Experimental results

Atli-Veltin, B. (author), Coppejans, O.J. (author), Hoogeland, M. (author), van Bergen, J.W. (author)

Increasing resistance against impact, either from other ships, floating objects or icebergs, will make shipping safer. Lean Duplex, which is in the stainless steel family, has high strength, and corrosion resistance. Lean Duplex is investigated focusing on its crash resistance in raking scenarios as part of an ongoing project. Material...

A survey of health monitoring techniques for the dutch transportation infrastructure

Wessels, J.F.M. (author), van der Mark, P.J. (author), Bektas, K.E. (author), Bakker, J. (author), van der Voort, M. (author)

Transportation infrastructure assets are designed to meet pre-specified reliability, availability, maintainability and safety (RAMS) requirements. Electrical and mechanical components are critical elements with respect to the RAMS-criteria. Unplanned failure of these components lead to societal impact, unsafe situations or costs. The trend in...

Information requirements for effective management of an ageing transport network

Paulissen, J.H. (author), van Es, S.H.J. (author), Peelen, W.H.A. (author), Klatter, H.E. (author)

In this paper the budget prognosis and the technical end of service life issues of the transport infrastructure replacement program of Rijkswaterstaat are introduced. Furthermore the technical information required to execute the program in a cost-effective way while keeping the infrastructure safe and available is discussed. For fatigue and...

Working towards one and the same objective: how serious gaming makes storm surge barriers more reliable

Schelland, M. (author), Huibregtse, J.N. (author), Walraven, M. (author), Bouwman, E.C.J. (author)

Various changes have put the retention of knowledge within Rijkswaterstaat (the executive agency of the Dutch Ministry of Infrastructure) under pressure in the past years. For crucial objects such as the storm surge barriers, a loss of knowledge is not acceptable and is hence addressed in multiple ways. This paper focuses on the context, content...

Asset information management using linked data for the life-cycle of roads

Luiten, B. (author), Bohms, M. (author), Alsem, D. (author), O’Keeffe, A. (author)

From September 2016 to August 2018 a CEDR (Conference of European Directors of Roads) research has been conducted by the consortium INTERLINK into asset information management for European Roads life-cycle management using Linked Data. This research aims to improve interoperability between the European National Road Authorities (NRAs) and their...

Target reliability indices for existing quay walls derived on the basis of the LQI criterion

Roubos, A.A. (author), Allaix, D.L. (author), Steenbergen, R.D.J.M. (author), Fischer, K. (author), Jonkman, S.N. (author)

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 ...

Use of a future maintenance demand indicator for network level asset management decision making

van Meerveld, H. (author), Schoenmaker, R. (author), Wessels, J.F.M. (author), Bakker, J. (author)

This paper discusses the development and first testing of a valid, reliable, functional and simple indicator, that represents the long term effect of short term decisions. Such an indicator can assist counteracting short term views in network level asset management decision making. Short-termism or myopia may occur in cases where service level...

Padé approximation of delays in CACC-controlled string-stable platoons

Xing, H. (author), Ploeg, J. (author), Nijmeijer, H. (author)

Cooperative Adaptive Cruise Control (CACC) improves road throughput by employing intervehicle wireless communications. The inherent communication time delay significantly limits the minimum inter-vehicle distance in view of string stability. Applying a Padé approximation leads to a model with a rational transfer function, which allows many...

Improved method to calculate additional ramps explicitly (CARE2) in quantitative risk analysis for road tunnels

Nelisse, R.M.L. (author), Vrouwenvelder, A.C.W.M. (author)

Article 13 of the EU Directive on minimum safety requirements for tunnels in the Trans-European Road Network states that a risk analysis, where necessary, shall be carried out. In the Netherlands, the risk of death for road users in a tunnel is calculated with a model for quantitative risk analysis, which is called “QRA-tunnels”. QRA-tunnels is...

The effect of mixing sequence on the workability and indirect tensile strength of asphalt concrete

Voskuilen, J. (author), Gaarkeuken, B. (author), van Vliet, D. (author), Poot, M. (author)

The KGO mixing method was developed 40 years ago. Instead of adding the bitumen at the end of the mixing cycle, the bitumen was poured down first together with the larger aggregates. After mixing the bitumen with the larger aggregates, the reamining aggregates were mixed down. As benefits of the KGO method were mentioned improving the...

Long-term performance of marine structures in the Netherlands - validation of predictive models for chloride ingress

van Breugel, K. (author), Polder, R.B. (author), de Rooij, M.R. (author)

For many concrete infrastructural works a service life of 80, 100 or 200 years is required. To convince owners and authorities that these requirements can be met probability-based models for service life predictions have been developed. These models are based on theoretical and experimental laboratory studies. Many of these models focus on the...

Safety requirements for buildings under induced earthquakes due to gas extraction

Steenbergen, R.D.J.M. (author), Vrouwenvelder, A.C.W.M. (author)

In the Dutch province of Groningen over the last year shallow earthquakes are induced due to large scale gas extraction from the gas field at 3 km depth. The induced earthquakes differ from the better known tectonic earthquakes all over the world, caused by movement of the earth at large depths. The structures affected by the earthquakes however...

Cost benefit analysis of monitoring modular joints in the dutch highway network

Peelen, W.H.A. (author), Vervuurt, A.H.J.M. (author)

Modular expansion joints constitute a substantial part of direct and indirect costs of bridge maintenance. Joint condition assessments can be improved to predict or detect damages earlier. In this way the probability for consequential damages such as emergency repair and a shortened lifespan is reduced. Maintenance can be planned well in advance...

Quality control during the construction process is one of the determining factors that governs the service life of an asphalt road. In CONSISTEND a predictive tool is developed that objectively determines the effect of quality control during the construction processes on the life span of surface courses of asphalt roads. The tool predicts the...

A system approach for replacement strategy of hydraulic structures

van der Wiel, W.D. (author), Klanker, G. (author), Klerk, W.J. (author), Persoon, E. (author), Wessels, J. (author), de Wit, A. (author)

Many of the Dutch movable hydraulic structures are exceeding lifetime expectancy based on the then-current standards and regulations. Also signs of ageing become apparent, regulations (e.g. about structural safety) get more and more strict and functional requirements have often increased over time due to climate change and socio-economic...

Inspection and maintenance optimization for OWT’s using Bayesian networks

Courage, W.M.G. (author), Nicoreac, M.P. (author), Kempker, P.L. (author)

For offshore wind turbines (OWT’s) environmental and accessibility conditions make inspection and maintenance costly. Hence the potential of cost reduction when the planning of these actions can be optimized. Taking uncertainties into account, a risk based concept is adopted in which probabilities of failure and its consequences are balanced...
