Behaviour and analysis of a reinforced concrete box girder bridge

Abstract

Le but de cette étude fut d'examiner la résistance et le comportement d'un pont a poutres-caisson en béton arme soumis à décharges symétriques et asymétriques. La phase expérimentale consistait en des tests sur un modèle réduit a l'échelle 1/2.82 d'une travée intermédiaire d'un pont a poutres caisson continu. Les rigidités un flexion et en torsion de la poutre-:'caisson ont diminué avec une augmentation de la charge appliquée à cause de la formation et de la propagation des fissures et de l'inélasticité du béton. Le fléchissement de l'âme chargée a été deux fois supérieur à celui de !'&me non-chargée; de plus dans les deux cas de chargement, les déplacements latéraux et expérimentaux ont varié d'environ 5 à 8 pour cent des déplacements verticaux de la section médiane de la portée.

This study was aimed at investigating the strength and deformational behaviour of a reinforced concrete box girder bridge under symmetrical and unsymmetrical loading conditions. The experimental phase consisted of tests on a 1/2.82 scale, direct model of the intermediate span of a continuous box girder bridge. The flexural and torsional stiffnesses of the box girder decreased with an increase in the applied load due to the formation and propagation of cracks and inelasticity of concrete. The loaded web showed a deflection of about twice that for the unloaded web; also, the lateral and longitudinal displacements of both webs varied from about 5 per cent to 8 per cent of the respective midspan vertical deflections.
