CFRP Reinforced RC Beams
Test setup, specimen details and material properties
Four beams were manufactured and tested with total length of 2.7 m. They were 140 mm wide with the effective depth of 220 mm. The beams were reinforced with longitudinal deformed bars and vertical closed ligatures made of plain bars. The composites FRP bonded on the soffit of the beams were 100 mm wide.
The concrete material used was supplied separately, pre-mixed from a local supplier. Compressive tests were carried out in accordance with AS1012.9-1999 (Standards Australia, 1999). The concrete strengths at the day of the first test in the series were 53.7 MPa (67 days), respectively.
Assessment requirement
1. For the strengthened and control beam, calculate the load required to cause all possible failure modes for each beam. Including: flexural failure, shear failure, IC debonding failure, concrete cover separation failure, longitudinal shear stresses and anchorage failure.
2. State the governing theoretical failure load and mode and compare it with the experimental results.
3. Discuss any differences between your theoretical predictions and experimental findings.
4. Assume that a U-jacked anchorage system has been placed at the end of the CFRP for the E series beams which suppresses concrete cover separation failure. Recalculate the theoretical failure load and discuss any observations.
