Redistribution of Bending Moment in Continuous Concrete Beams Reinforced with Glass Fibre Reinforced Polymer

Popis výsledku v původním jazyce

The aim of this paper is to investigate the behaviour of concrete continuous beams with domestic GFRP reinforcement. In addition authors focused on the moment redistribution effect in GFRP-reinforced concrete continuous beams. Three beams with differentGFRP reinforcement configuration were examined in this paper and compared to the steel-reinforced concrete continuous beam. Concrete continuous beams were 3800 mm long with two uneven spans. One span was 2300 mm long; the other span was 1500 mm long. Thecross section of the beams was 130 mm wide and 180 mm high. Point load, deflection and all support reactions were monitored during the experimental program. Load-deflection diagrams of the GFRP-reinforced concrete continuous beams were bi-linear as GFRPrebars had no yield point and no plastic plateau. It was verified experimentally that GFRP-reinforced concrete continuous beam with reinforcement ratio 0.24, 0.43 and 0.67 is able to redistribute 32 %, 28 % and 33 % of moments, respectiv
