Évaluation sous charges statiques de glissières de ponts de type PL-2 et PL-3 en béton renforcé avec de l'armature en matériaux composites

Abstract

Our very particular environmental conditions place our concrete bridge barrier walls in a very aggressive environment from which an acceleration of the process of corrosion of the steel reinforcement and possibly the bursting of the concrete will occur. This degradation seriously damages the structural integrity of the barrier walls, reduce their capacity of shock resistance and their lifespan. An experimental program of static tests on barrier walls of the types PL2 and PL3 reinforced with composite material was undertaken at the department of civil engineering of the university of Sherbrooke. The initial stage consisted in carrying out theoretical and comparative analysis on barrier walls of the types PL2 and PL3 reinforced with Isorod bars. The steel and Isorod reinforcements, as well as the concrete were analysed with electric gauges to measure the deformations according to the load applied."--Résumé abrégé par UMI
