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...

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...

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...

To develop climate proof road infrastructure it is of importance to understand the quantitative effects of expected climate change on the performance of individual components, such as tunnels and road sections, and their contributions to the performance of the overall road network.A full understanding of quantitative effects on infrastructure...

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

The provisions for wind loads on flat roofs differ considerably between current wind loading standards in different jurisdictions. For a number of major wind loading codes, both the definition of roof zones, and the values applied to determine the wind loads are discussed. This paper concentrates on the wind loading zones near edges and corners,...

The 'Hovenring' is a bicycle roundabout flyover built as a signature bridge with a central steel pylon carrying a circular bridge deck suspended through stay-cables. Shortly after installation of the bridge, the stay-cables turned out to vibrate in the wind due to vortex shedding. These vibrations have possibly caused fatigue damage in the...

An effective application of Very High Strength Steels (VHSS) can be expected in truss-like structures, typically made of hollow sections. Improved design of VHSS truss structures could incorporate the application of cast joints, since an appropriate design of cast joints limits the stress concentrations in the joint and welds are shifted out of...

Orthotropic deck structures are used in many steel bridges. Due to the typical detailing applied as around 1970, a significant number of deck structures constructed in that period suffer from fatigue damage. In many countries cracks have been detected, in particular in the weld between the deck plate and the trapezoidal stiffener. These cracks...

Modal properties of high rise buildings are mostly derived from measurements on existing buildings under dynamic random wind loading. Measured accelerometer signals are translated into values for the natural frequency and damping. In order to obtain reliable values for the modal properties, the distillation of these parameters from the measured...

This paper presents a research project in The Netherlands in which a large number of stakeholders are collaborating on a 3D test bed, selected use cases and a test area to push 3D applications in the Netherlands. The project studies and realizes a proof of oncept for a 3D Spatial Data Infrastructure, that addresses issues ranging from 3D data...

In 2008 is in de rechter rijstroken van de A32 nabij Wolvega (aangelegd in 1986-1988) de asfaltverharding met hoogovenslakkenfundering op een aantal plaatsen onverwacht en vrij abrupt bezweken. Er ontstonden flinke verzakkingen en daarin vertoonde de asfaltverharding ernstige scheurvorming. Draagkrachtmetingen toonden aan dat de fundering over...

The lateral torsional buckling resistance of girders depends on the support conditions. In floor structures for buildings, coped girders are often used. A numerical model was developed to research the influence of copes on lateral buckling resistance. The model is successfully validated with tests. This paper describes the background of the...
