MOMENT REDISTRIBUTION IN CONTINUOUS FRP REINFORCED CONCRETE BEAMS

This paper discusses the issue of redistribution of stresses and moments in continuous FRP reinforced concrete beams. Six 6.5 m long two-span FRP reinforced concrete beams were designed and constructed. While two of the beams were reinforced with steel as control specimens, the other four were longitudinally reinforced with CFRP rods. Analysis of results showed considerable amount of redistribution for FRP over-reinforced concrete beams while the amount of redistribution for FRP under-reinforced concrete beams was negligible.
