Fatigue of Concrete Slabs Pre-stressed with CFRP Tendons
Original language description
Service life of steel-reinforced concrete structures is in many cases limited by the durability of the reinforcement itself. There are several possibilities how to improve corrosion resistance but none of these measures or its combination has proved to eliminate the long-term risk of steel corrosion. For this reason in recent years non-metallic reinforcement, such as fibre reinforced polymers (FRP), has gained great deal of interest by many researchers. Because of its promising properties, FRP bars havebeen studied all over the world. The main research areas include durability of FRP bars in alkaline environment, flexure and shear behaviour of structures reinforced with either normal or pre-tensioned FRP reinforcement. However, virtually no work has been in done in terms of fatigue of concrete members pretensioned with FRP tendons.
