Partial factors are commonly based on expert judgements and on calibration to previous design formats. This inevitably results in unbalanced structural reliability for different types of construction materials, loads and limit states. Probabilistic calibration makes it possible to account for plentiful requirements on structural performance,...

This summer, all over Europe, record temperatures have been measured. From my own country, the Netherlands, the people working at the various meteorology organisations never imagined that the temperature in more than half the country would reach above 40°C. And yet it did! Another example that the climate is changing

Circularity is an increasingly often mentioned ambition of governments of various levels, yet the translation into concrete plans and policies is limited. The Metropole Region of Amsterdam (MRA) is a pioneer in this field, initiating a research for circular rebuilding of a neighbourhood in 2016 and the development of a roadmap for circular urban...

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...

The quality of local skin temperature prediction by thermophysiological models depends on the local skin blood flow (SBF) control functions. These equations were derived for low activity levels (0.8-1 met ) and mostly in sitting or supine position. This study validates and discusses the prediction of foot SBF during activities of 1-3 met in male...

Cement paste is the glue that holds concrete together and any improvements in material performance will come from its microstructure. For better understanding and predicting its elastic properties and fracture performance, more and more studies are carried out based on micromechanics simulations. However, the predicted results can be hardly...

Design codes and standards rely on generalised target reliability indices. It is unclear, however, whether these indices are applicable to the specific risk-profile of marine structures. In this study, target reliability indices for quay walls were derived from various risk acceptance criteria, such as economic optimisation, individual risk (IR)...

Wat is RESPONSE? Bij een incident met gevaarlijke stoffen heeft Response drie functies: 1. Berekenen van de bronlocatie van het incident, onder meer op basis van sensordata of klachten van omwonenden; 2. Berekenen van de mogelijke effecten van het incident met een gevaarlijke stof voor de omgeving; 3. Selecteren van informatie voor werknemers en...

Interaction of ultrasonic waves with partially-closed surface-breaking cracks in concrete structures has been studied. Measurements have been conducted on a reinforced concrete beam containing various mechanical-load-induced cracks and compared with the baseline measurements at those locations. Influence of crack width, incident angle of waves...

In structural reliability the dependence structure between random variables is almost exclusively modeled by Gauss (normal or Gaussian) copula; however, this implicit assumption is typically not corroborated. This paper is focusing on time-variant reliability problems with continuous stochastic processes, which are collection of dependent random...

Backside ventilation is one of the most common passive cooling methods of PV modules in the built environment, but might be under constraint when integrating PV in the building envelope. To investigate the short and long term effect of backside ventilation on Building Integrated PV (BIPV) performance and lifespan, a comparative BIPV field test...

Natural environments (NE) are promoted as places that support physical activity (PA), but evidence on PA distribution across various types and sizes of NE is lacking. Accelerometers and GPS-devices measured PA of Dutch general population adults aged 45–65 years (N=279). Five NE types were distinguished: ‘parks’, ‘recreational area’, ...

In theorie naderen veel bruggen en viaducten hun einde levensduur, maar de soep wordt niet zo heet gegeten als zij wordt opge-diend. Veel kunstwerken bezitten verborgen krachten. Toch is het nodig alle over-spanningen goed in kaart te brengen en kennis over dit onderwerp met elkaar te delen en/of op te bouwen

Through the comparison of several regional-scale chemistry transport modeling systems that simulate meteorology and air quality over the European and North American continents, this study aims at (i) apportioning error to the responsible processes using timescale analysis, (ii) helping to detect causes of model error, and (iii) identifying the...

Het Lint is een ruim 8km lang beweeglint in het Máximapark in Utrecht dat intensief wordt gebruikt om te wandelen, fietsen, skaten, hardlopen. Een groot succes dus, maar wat verklaart dit succes? Wat zijn de randvoorwaarden en ontwerpprincipes die misschien ook elders voor succesvolle toepassingen kunnen zorgen? Deze vraag stelde de gemeente...

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...

It is the purpose of this study to investigate thermal sensation (TS) and thermal comfort (TC) in changing environments. Therefore, 10 subjects stayed in a 30 °C, 50% relative humidity for 30 min in summer clothes and then moved to a 20 °C room where they remained seated for 30 min (Hot to Reference - HR). Similarly, 11 subjects moved from a 10 ...
