Flexural capacity of the CFRP prestressed concrete slabs subjected to sustained & fatigue loading

Popis výsledku v původním jazyce

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 fifteen 4.5-metre-long concrete slabs were casted. Each slab was prestressed with five CFRP bars. Eight slabs were subjected to static - four point bending test. Six slabs were subjected to fatigue and one slab was subjected to sustained loading for one year. It wasverified experimentally that high-cycle fatigue has no significant effect on the flexural capacity of the slab.
