Abstract EN
This paper presents results from experiments on aged and seriously damaged reinforced concrete (RC) beams strengthened with different arrangements of external carbon fiber-reinforced polymer (CFRP) laminates and end anchorages.
Seven RC beams from an old bridge, measuring 250 × 200 × 2300 mm, were tested.
All specimens were loaded to yield load to evaluate initial mechanical properties.
Then, these seriously damaged specimens were repaired using different CFRP-reinforcing schemes and reloaded to failure.
The yield load growth due to CFRP reinforcement ranged from 5% to 36%.
Different parameters including CFRP dimension and position, bonding length, and end anchorage were investigated and facilitated conclusions on beam ductility, load-midspan deflection response, and failure mode.
This research contributes to knowledge about the CFRP repair of aged and seriously damaged beams to ensure better performance in overloaded conditions.
