In the context of the STREST project (http://www.strest-eu.org/), an engineering multi-level risk-based methodology to stress test critical non-nuclear infrastructures has been developed. This paper summarizes the STREST framework and its exploratory application to six key representative Critical infrastructures in Europe, exposed to variant...

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...

Pipeline networks for gas and water are the lifelines of our society. Their presence and correct functioning translates in benefits and any disruption, malfunctioning or ruptures represent hazards for the community. Most pipelines are buried, which impedes direct monitoring of the structural reliability of the networks. The behavior of the soil...

design driver for Offshore Wind Turbine (OWT) substructures and also has an im-pact on operational costs. During service life, inspections are required to detect fa-tigue cracks at an early stage. These cracks may need to be repaired. The costs of in-spections and repair are high for offshore structures. To reduce the cost of energy, it is...

Markov-based models for predicting deterioration for civil infrastructures are widely recognized as suitable tools addressing this mechanism. The objective of this paper is to provide insights regarding a network of orthotropic steel bridges in terms of degradation. Consequently, a model combining a dynamic Bayesian network and a Markov chain is...

This paper presents a monitoring and modelling methodology to assess the current and future conditions of steel bridges subjected to fatigue cracking. Steel bridges are subjected to fatigue cracking as a result of fluctuating stresses caused by the crossing of heavy vehicles. Specifically for orthotropic steel bridge decks, fatigue cracking is...

Cathodic protection (CP) of reinforcing steel has been applied successfully to concrete structures with corrosion damage for more than 25 years. Performance and maintenance data are reported from an inventory of CP systems in The Netherlands installed on about 100 structures between 1987 and 2010. The large majority provides corrosion protection...

Nowadays, maintenance of wooden window frames strongly depends on the practical experience of the parties involved. To get a better understanding of the required maintenance period and maintenance actions, a model has been developed to predict durability. This model makes it possible to optimize maintenance in relation to the required quality,...

Underground infrastructures can fail due to ground movements. Due to the underground nature this is difficult to detect above ground. In a collaboration of multiple research institutes a new approach has been developed to estimate the probability of failure using underground position sensors. A Proof of Principle monitoring system was developed...

A risk-based safety approach is indispensable to support decision-making on flood protection strategies and measures. In most deltaic areas, flood risk analysis involves more than analysing the flood hazard and the potential damage, and flood defence systems also play an important role. In such systems consisting of rivers, estuaries and flood...

Steel is discarded by railway owners as a material for underground structures near railway lines, due to uncertainty over increased corrosion by DC stray currents stemming from the traction power system. This paper presents a large scale field test in which stray currents interference of a sheet pile wall was monitored in realistic conditions....

Voor de bepaling van het dwarskrachtdraagvermogen van constructies is de betonsterkte één van de bepalende parameters. Die neemt onder invloed van doorgaande hydratatie in de tijd sterk toe. Bij de beoordeling van kunstwerken kan gebruik worden gemaakt van de feitelijk aanwezige sterkte. Hierdoor kunnen kunstwerken worden goedgekeurd die in...

Based on construction dates and observed time to corrosion induced damage, the future need for repair of reinforced concrete motorway bridges in The Netherlands is predicted. Due to the age distribution and in particular the relatively short life of conventional repairs, the need for maintenance will increase steeply over the next few decades....

In general the condition of a structure can be assessed in terms of a performance indicator. For example, this can be the strength of a structure. An asset manager is concerned with ensuring that the performance of a structure does not fall below a given minimum level. This can be achieved by inspecting or monitoring the structure. As the...

Steel structures near DC powered railways are expected to be affected by stray current interference. This causes accelerated corrosion rates. Therefore steel is often not used as a building material in these cases, although certain advantages over the alternative material concrete exist. These advantages can include amongst others costs, shorter...
