Bond behaviour of FRP shear reinforcement on I-sections Universiteit Gent
Although external fibre reinforced polymer (FRP) reinforcements are easy to manipulate around any shape, their behaviour varies with respect to the geometry of the strengthened cross sections. This is in particular the case for shear strengthening of I-sections, such as prestressed concrete girders. The externally bonded (EBR) FRP shear reinforcement is susceptible to early debonding around the internal angles at the web-flange interface. Due to ...
