Development and validation of a numerical model for buckling of coped beams

The lateral torsional buckling resistance of a beam depends on the support conditions. In structures for buildings, coped beams are often used. A numerical model is developed to investigate the influence of copes on the lateral buckling resistance. The model was verified with laboratory tests. This paper describes the background of the numerical...

Fatigue tests on aluminium bridges

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...

Fire exposed aluminium structures

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...

Ontwerp en berekening van aluminium bruggen. Construeren in aluminium (11).

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...

Buckling of coped steel beams and steel beams with partial endplates

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...

Numerical simulation of lateral-torsional buckling of coped girders

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...

Lateral-torsional buckling capacities of coped girders

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...
