Flexural capacity of the CFRP prestressed concrete slabs
Original language description
The behaviour of concrete slabs with prestressed carbon fibre reinforced polymer (CFRP) composite bars is investigated in this paper. The main advantage of CFRP bars is their high strength/self-weight ratio. On the other hand, Young's modulus is lower compared to steel reinforcement which is the main cause for large deflections. To eliminate such deflections and to utilize high tensile strength of CFRP bars it is extremely useful to prestress the bars. During the experimental work a set of twelve 4.5-metre-long concrete slabs was casted. Each slab was prestressed with five CFRP bars. Six slabs were subjected to static - four points bending test. Five slabs were subjected to fatigue test and one slab was subjected to sustained load for one year.
