Strengthening of reinforced concrete (RC) structures with fiber reinforced plastics has become an increasingly popular method. In this research, the effectiveness of aramid fiber sheet (AFS) in strengthening RC bridge slabs subjected to fatigue wheel load is investigated. The specimens were subjected to initial damage before bonding of AFS in grid pattern. Fatigue tests by using wheel running machine were conducted. Experimental results reveal that the AFS is capable in improving the fatigue durability by expanding the service lifespan of non-strengthened slab |
