Bij de evaluatie van de veiligheid van monumentale gebouwen is de focus meestal gericht op de stabiliteit van dragende bouwdelen. Weinig of geen aandacht wordt in de regel besteed aan constructieve onderdelen die tot doel hebben gevelpanelen of ornamenten te verankeren. Toch kan aantasting van ijzeren of stalen verankeringen met de tijd, door...

People are more than 80% of their time indoors. However, in contrast to ambient air, no (legal) limits for indoor particulate matter exist. This paper describes a measurement protocol to determine the yearly averaged indoor PM2,5 concentration and gives reference values for five quality classes: <2,5 μg/m3 (A+), <10 μg/m3 (A: WHO annual advisory...

Within the European project RETROKIT a systemic approach is being developed for retrofitting existing multi-family residential buildings. Modular combination of (semi-) prefabricated technological solutions will be demonstrated in three case studies. The part of the study described here aims to evaluate the consequences of the retrofit process...

This paper describes the research and development of the Dutch national standard for information levels of BIM. The US-developed "Levels of Development" (LOD) have become increasingly popular in the Netherlands. However, more and more projects felt the need to develop an additional LOD250 and LDO350. It became clear that the Dutch design-and...

Every four years the Dutch government and the executive agency Rijkswaterstaat (RWS) negotiate a Service Level Agreement (SLA) for the performance of the national roads, waterways and water systems. In this SLA, the required performance of the infrastructure, the risks and the maintenance budget for the coming four years is agreed upon. The...

This paper addresses questions that arose during development and application of the Dutch guideline for wind tunnel testing to determine wind loads on buildings. This guideline (CUR 103) is being used since 2005, and a first revision is foreseen. Within this revision, the relation with Eurocode EN 1991- 1-4 is established. Questions to be...

Pressure measurements were performed on various configurations of two high-rise building models in two atmospheric boundary layer wind tunnels in the Netherlands. A comparison was made of the interference factors of the minimum and maximum peak pressures over all pressure taps at 0 degree angle of incidence obtained for measurements on the...

Fatigue cracks in orthotropic bridge decks are an important cause for the necessary renovation of existing bridges. Parallel utilization of various technologies based on different physical sensing principles can potentially maximize the efficiency of structural health monitoring (SHM) systems for these complex structures. A multidisciplinary SHM...

Collective self-organised (CSO) housing refers to the process of a collective of individuals that organize, finance, plan and commission their own housing projects. CSO housing can refer both to new construction, and retrofitting /refurbishment processes. The unique feature of CSO housing is the fact that CSO housing projects are undertaken by a...

Construction and maintenance activities of bridges often bring negative impacts to the urban environment in terms of disturbance, traffic jams and disruptions, noise, dust, and air pollution. Lack of coordination between the stakeholders in strategic, tactical and operational construction planning process has been identified as a key factor...

Noise mapping models are able to accurately predict directly exposed facade levels near busy roads on condition that sufäciently detailed trafäc data is available. At the non-directly exposed side ofthe building, howeve¡ common practice application of standard methods strongly underpredicts sound pressure levels, potentially leading to an...

Pressure measurements on a square plan form high-rise building model and two square high-rise building models in side-by-side arrangement were analysed using the Fast Fourier Transform (FFT) to define peak frequencies resulting from interference. For the isolated building model, a reduced frequency fred = fB/UH = 0.08 was determined on the side...

High-speed stereo-PIV measurements were performed in the wake of 2.3 m wide fences (respectively 5 and 10 cm high). Average velocities and turbulent kinetic energy levels are given for a near fenceand a downstream field of view, showing the large recirculation zone of a near-2D obstacle. The results indicate that although PIV measurements can...

European bridges are today in a state of particular concern with over 50% of European urban bridges being more than 40 years old and thus requiring considerable maintenance or possibly even replacement [1]. This means that interventions in the present infrastructure have to be made while ensuring that mobility continues in a safe and consistent...

Recent developments in acoustic monitoring systems make it possible to measure complex noise situations, like urban traffic noise, continuously. Monitoring provides more insight in the noise situation, from which more specific and (cost) effective measures can be taken. Monitoring also allows direct evaluation of the effect of mitigation, or to...

For the assessment of the in situ compressive strength in structures and precast concrete components EN 13791 applies. Among others, this standard may be adopted when doubt arises about the compressive strength in the structure. However, for assessing the structural safety of existing structures of many years of age, the method given in EN 13791...

In the Netherlands the State Public Works is responsible for the main waterway network, where locks are mostly the decisive bottlenecks in the navigation corridors. In the last decade the State Public Works has changed from a technical oriented maintenance organization mainly focussed at the component and asset level to a user oriented service...

Forces on multi-span gable roof buildings with different height/width ratios have been measured to investigate the effect of the number of bays on the horizontal component of the wind force. It has been found that with increasing number of bays, the horizontal wind force increases proportionally
