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...

The lateral torsional buckling resistance of girders depends on the support conditions. In floor structures for buildings coped girders are often used. In a recent study, a numerical model was developed to investigate the influence of copes on the lateral buckling resistance. This model is described in an companion paper [ 1 J. In this paper...

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...

Copes and partial endplates influence the resistance to lateral buckling of a steel beam. In order to quantify this influence, numerical research has been carried out with validated models. Full-scale laboratory tests carried out for the validation of the numerical models are described in the Annex to this paper. The research resulted in...

Material properties and mechanical response models for fire design of steel structures are based on extensive research and experience. Contrarily, the behaviour of aluminium load bearing structures exposed to fire is relatively unexplored. This article gives an overview of physical and mechanical properties at elevated temperature of frequently...

because aluminium is sensitive to elevated temperatures, considerable attention is required on the fire design of aluminium structures. In this respect, the heating of aluminium is evaluated as well as the structural response when exposed to fire. It shown that the application of advanced models in the design results in more optimal designs

Dragende constructiedelen van aluminium legeringen, zoals toegepast in bouwconstructies maar ook in schepen en offshore platforms, moeten zodanig ontworpen worden dat mensen veilig kunnen vluchten als er brand uitbreekt. Door de lage smelttemperatuur van aluminium vraagt brand de nodige aandacht in het ontwerp. Er is echter weinig onderzoek...

Veel stalen bruggen in Nederland hebben een zogenoemd orthotroop rijdek (een rijde met troggen en dwarsliggers als verstijving), zoals weergegeven in figuur 5.1. Ook het de van de Brienenoordbrug bestaat uit een orthotroop rijdek. Vanwege vermoeiingssc euren moest het brugdek van de ophaalbrug in de Brienenoordbrug reeds binnen enkele jaren na...

The use of pre-cast concrete floor slabs in steel framed structures is quite common. In the de-sign of the steel beams, the lateral restraining effect of the pre-cast concrete slab is normally safely neglected. However, the concrete slab will provide some horizontal restraint, even without special provisions such as dowels being present. It may...

There is a tendency to use aluminium as structural material in heavily loaded structures. In a number of these structures, the resistance to fire should be considered in the structural design. Because of the low melting temperature of aluminium, aluminium structures are sensitive to fire and extra attention of the designer is required in this...
