- Description
- The paper describes an experimental investigation into the long term deflection behaviour of reinforced concrete (RC) beams strengthened externally with epoxy bonded Fibre Reinforced Polymer (FRP) strips. A possibility being examined is that under the sustained loading, creep in the epoxy adhesive will allow the FRP strips to unload, leaving them ineffective against the sustained load. The deflections of two RC beams, one with FRP strips and one without, as well as slip movements at the ends of the FRP strips have been monitored over time. The experimentally measured long term beam deflections were compared to deflection predictions using two different analytical approaches. The results to date indicate that creep in the particular adhesive used is small but perhaps not insignificant. To ensure that unloading of externally bonded FRP reinforcement does not occur under sustained loads, some form of mechanical anchorage is recommended.
