A Preliminary Study of New Anchorage Designs for Strengthening RC Beams with Externally Bonded FRP Composite Materials
ln the past twenty years a great deal of research has been conducted on the use of externally bonded CFRP sheets for strengthening RC beams. It has been found that various anchorage designs at the ends of the bonded sheets could lead to different load-deflection characteristics and failure modes in the beams. This study presents results from an experimental study on new anchorage designs for strengthening RC Beams in flexure with externa1ly bonded CFRP sheets. Nine specimens were tested in four-point bending. The test variables include anchorage design, bond length, and mid-span bond. Anchorage is achieved by a mechanism that clamps the sheet-ends into a groove that is cut into the tension side of the RC beam. Two clamping approaches are adopted. One employs a bolted steel bar and rubber bearing pad; the other employs a plug and epoxy filling.
