Tuff stone elements with a large length/width ratio often suffer damage in the form of cracks parallel to the surface and spalling of the outer layer. The response of tuff to moisture might be a reason for this behaviour. This research aimed at verifying if differential dilation between parts with different moisture content (as outer and inner...

In many cultures in the past, sustainability used to be an integral concept, related to building traditions, crafts and daily life.With the increasing complexity of our society and the progressive shift from the local to the global scale the past sustainable building tradition has often faded out, without being substituted by a new, equally...

Blast furnace slag cement (BFSC) has been used in reinforced concrete structures in marine and road environment in The Netherlands for nearly a century. Experience is good and long service lives can be obtained. In Norway experience with BFSC is scarce. In The Netherlands, a high resistance against chloride penetration and a high electrical...

Het Domplein in Utrecht bevindt zich op de plaats van het Romeinse castellum Traiectum (Fig. 1), onderdeel van de verdedigingslinie langs de noordgrens van het Romeinse rijk, de zogenaamde limes. Het Domplein heeft een complexe geschiedenis. Binnen de muren van het castellum zijn verschillende kerken gebouwd en weer gesloopt. De huidige...

Microscopsch (petrografisch) onderzoek van mortels dient een tweeledig doel: het vaststellen van de aard van aantasting van een mortel, of het bepalen van de samenstelling daarvan. Voor dat laatste is het een alternatieve bron naast historische (besteks)gegevens. De microscopisch verkregen informatie is een belangrijk uitgangspunt voor de keuze...

Although salt crystallization damage is a widespread damage process in the porous materials of our built cultural heritage, no definite solution yet exists to improve the durability of materials with respect to salt crystallization. Most research focuses on improving material properties, whereas only few studies concentrate on changing the...

Façade elements are themost vulnerable parts of buildings with respect to wind loading. In this paper it is assessed to what extent wind-loaded façade elements fulfill the minimum reliability requirements as set in the Eurocodes. The reliability analysis needed for this assessment should account for the uncertainties in each of the parameters...

The number of monitoring pilots in Dutch civil infrastructure with sensing systems is increasing only slowly over the last decade. To identify and help understand barriers for wider implementation of moni-toring systems, SBRCURnet-committee 1992 analysed 13 monitoring pilots. The committee consisted of 16 Dutch infrastructure owners,...

Where exposed to an aggressive environment, concrete structures will develop reinforcement corrosion at some point in their life. Chloride ions from de-icing salt or sea water induce pitting corrosion. Local cross section reduction may occur relatively quickly and expansion due to corrosion products precipitating may crack and spall concrete...

Fatigue life or crack growth predictions that use information from crack inspections have been applied to offshore structures and, in recent years, also to steel bridges. Apart from inspection data, a probabilistic crack growth model and knowledge of the distributions and correlations of the variables are required for such predictions. The...

Aluminium plates containing a single hole or multiple holes in a row are recently becoming very popular among architects and consultant engineers in many constructional applications, due to their reduced weight, as well as facilitating ventilation and light penetration of the buildings. However, there are still uncertainties concerning their...

Salt crystallization is one of the most common causes of decay of porous building materials. Salts can cause damage when they, due to the presence of moisture, undergo crystallization/dissolution cycles. Removing the moisture source can

Asfalt heeft de aantrekkelijke eigenschap dat het zichzelf kan herstellen na schade. Er is echter tot op heden geen betrouwbare methode om de healingcapaciteit van een asfaltmengsel te bepalen. Bij het healingproces van een discrete scheur spelen twee processen een rol, namelijk het in contact komen van de oppervlakken van de scheur; het...

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...

De veroudering van het asfalt bindmiddel is een van de belangrijkste eigenschappen die een invloed hebben op de levensduur van open deklagen. In deze paper wordt de ontwikkeling van de veroudering van bindmiddel in de weg en met kunstmatige veroudering in het laboratorium beschreven in termen van reologische eigenschappen (magnitude en fasehoek...
