Creep Behaviour and Residual Flexural Capacity of GFRP and CFRP Pretensioned Concrete Slabs

Popis výsledku v původním jazyce

The objective of this study is to examine the flexural behaviour of concrete slabs pretensioned withdomestic Glass Fibre Reinforced Polymers (GFRP) and Carbon Fibre Reinforced Polymers (CFRP) under sustained loading. In order to achieve this, set of twoconcrete slabs 4.5 meter long were examined. Concrete slabs were pretensioned with four and five reinforcing bars (rebars) in case of GFRP and CFRP reinforcement, respectively. Set of additional eleven slabs was casted for quasi-static loading. Quasi-static loading was performed in order to verify flexural capacity and to check residual flexuralcapacity of the slabs after sustained loading. It was verified experimentally that GFRP pretensioned concrete slab is not suitable for long-term loading due to massive deflection evolution in time. On the other hand CFRP pretensioned slab showed reasonable flexural behaviour in terms of deflection evolution and crack propagation. It was also concluded that sustained loading has no significant effe
