BIM opent volgens TNO mogelijkheden om een virtueel bouwwerk vooraf en een gerealiseerd bouwwerk achteraf automatisch te toetsen aan eisen van het Besluit bouwwerken leefomgeving (Bbl). Hiermee zijn in de toekomst zowel aannemers als private kwaliteitsborgers in staat om op verantwoorde wijze een bouwwerk bij oplevering te beoordelen op...

Fire safety is becoming an important theme for more and more healthcare organizations in the Netherlands. The compliance with the fire safety requirements of the Dutch Building Decree is not always conclusive and discussions with the local authorities on the interpretation and elaboration of the legislation for fire safety are emerging....

De bouw staat het komende decennium voor enorme uitdagingen om de vraag naar meer en betere gebouwen te faciliteren. Een extra lastige opgave, door de toenemende complexiteit van het bouwproces dat een aaneenschakeling is van deelprocessen waaraan steeds meer partijen gelijktijdig werken. Overschrijdingen van tijdplanningen en kosten lijken de...

It has been suggested that future generations of building regulations can become more risk-informed and performance based, and that development of the regulations and the risk bases that underpin them should occur within a socio-technical systems framework. To facilitate this, it is important for regulators and the market to understand and agree...

The demand of a risk-informed performance-based approach for fire safety is growing in the Netherlands. Various major incidents have initiated the need for an upgrade of fire safety regulations. All major stakeholders involved have noted that the existing regulations are limited and that a risk-based approach should be developed. The discussions...

Building regulatory systems have been evolving in recent decades, first with a transition to a functional or performance basis, and more recently with the introduction of new societal objectives, including those related to sustainability and climate change resiliency. Various policy and technical challenges have been identified with this...

On the morning of May 13, 2008, a fire that started in a coffee vending machine on the 6th floor of the 13-story Faculty of Architecture Building at the Delft University of Technology (TUD), Delft, the Netherlands, quickly developed into an extreme loading event. Although all building occupants evacuated safely, the rapid fire spread severely...

For toughened and flexible adhesives it is found that a simple prediction model for overlap joints can be used to calculate the ultimate strength for the static load case. The absolute maximum strength for a lap joint is when the whole of the adhesive layer is at the shear yield strength. An additional requirement regards yielding of the...

Applications of aluminium have grown considerably in building and civil engineering the last decade, which is due to various aspects: light weight, durability and maintenance, use of extrusions. The paper starts with a short history of aluminium bridges and then focuses on aluminium bridges in the Netherlands. The design of 58 bridges for an...

De gunstige sterkte-gewichtsverhouding en de duurzaamheid van aluminium maken het bij uitstek geschikt als constructie-materiaal voor beweegbare (verkeers)bruggen of voor de vervanging van houten brugdekken. Voor een materiaal met een dergelijk laag eigen gewicht geldt echter dat het gevoelig is voor vermoeiing, aangezien de variabele belasting...

Traffic bridges are subjected to variable loads and should therefore be checked on fatigue. Especially low weight materials, like aluminium, are sensitive to fatigue, because the variable load is a substantial part of the total load. This paper shows the structural design of an aluminium bridge loaded by heavy traffic. The S-N curves of a welded...

Since flexible adhesives are used more and more in structural applications, designers should have a better understanding of its behaviour under various conditions as ultimate load, fatigue load, long-term load and environmental conditions. This paper focuses on long-term load conditions and its effect on flexible adhesives. The creep properties...

Applications of aluminium have grown considerably in building and civil engineering the last decade. In building and civil engineering the increase of aluminium applications is due to various aspects like light weight, durability and maintenance, use of extrusions, and esthetics.

Using two types of adhesively bonded aluminium joints, a TAST specimen and a specifically designed stiff double lap joint, experiments show that the (apparent) yield stress, the amount of plastic flow and the occurence of strain hardening is influenced by the surface pre-treatment used for an Al-Mg-Si aluminium alloy adherend. Grit blasted...

Dit artikel behandelt de ontwikkeling van rekenregels voor het ontwerpen van lijmverbindingen in constructies. In de dagelijkse praktíjk worden constructeurs geconfronteerd met het probleem om de veiligheid van hun ontwerpen te controleren. De opzet van een experimenteel programma kan hierin voorzien. Voor de scheepvaart, de transportsector, de...
