FRP shear dowels as alternative reinforcement of concrete-to-concrete interface
Original language description
Strength of the interface between two concrete parts cast against at different times is governed by the properties of adhesive bond or amount of the reinforcement crossing the interface. If adequate surface preparation cannot be realized, or adhesion is insufficient, shear dowels were used to ensure monolithic behaviour of the specimen. In order to fully utilize shear reinforcement, it has to be assumed that adhesive bond is lost, and that crack will appear along the interface. Especially in the cases of vertical interfaces, those cracks can be main cause of many durability issues like corrosion of the reinforcement. For that reason, performance of FRP (Fibre Reinforced Polymers) shear dowels was investigated, representing durable alternative to commonly used steel dowels. Experimental investigation, including 4 different amounts of reinforcement and 30 specimens in total is performed. Push-Off test setup was chosen. In this paper, obtained results were presented, together with design approach for FRP dowels, including authors comments and recommendations for practice.
