Lateral Torsional Buckling of steel bridge girders

Jean-Paul Lebet, Raphaël Thiébaud

The Lateral Torsional Buckling (L.T.B.) design of beams in buildings has received considerable attention over the last decades, and relatively similar improved design rules are now implemented in major design standards. On the contrary, it may be shown tha ...

Résistance au déversement des poutres métalliques de pont

Raphaël Thiébaud

Steel and steel-concrete composite bridges made of plate girders represent an economical structural form and are largely used for short and medium spans. Two parallel plate girders connected by cross-beams define a twin-girder bridge. This type of bridge t ...

Resistance to LTB of steel bridge girders

Jean-Paul Lebet, Raphaël Thiébaud

Lateral torsional buckling (LTB), a complex phenomenon of instability, occurs when a beam is solicited by a bending force. In the area of steel and composite bridges girders which are characterised by slender plate girders, few experimental and theoretical ...

Experimental and numerical characterisation of heat flow during flame cutting of thick steel plates

Jean-Marie Drezet, Jean-Paul Lebet, Raphaël Thiébaud

Temperatures measurements during flame cutting of a thick steel plate and measurements of the extension of the fusion and heat affected zones and Vickers hardness after cutting have been performed. Additionally, a 3-D thermal model for simulation of flame- ...

Résistance au déversement des poutres métalliques de pont

Jean-Paul Lebet, Raphaël Thiébaud

Le déversement est un phénomène complexe d’instabilité qui intervient lorsqu’une poutre est sollicitée par un effort de flexion. De nombreuses recherches expérimentales et théoriques, dont les résultats servent de bases aux normes actuelles de la construct ...

Experimental study of residual stresses in thick steel plates

Jean-Paul Lebet, Raphaël Thiébaud

Residual stresses must be taken into account when evaluating the stability of a steel bridge girder. Residual stresses are unavoidable, as manufacturing processes for steel plates introduce thermal residual stresses in the material. For welded built-up sec ...

Experimental and numerical characterisation of heat flow during flame cutting of thick steel plates

Jean-Paul Lebet, Raphaël Thiébaud

This paper concentrates on the characterization of the heat flow present during flame cutting of 60 mm thick steel (S355N) flanges, a typical size used in the fabrication of bridge girders. Experimental results are associated with a finite element analysis ...
