Rehabilitation of Steel-concrete Composite Beams Using FRP

Usama A. Ameer

Abstract:
Using Fiber Reinforced Polymer (FRP) in rehabilitation of concrete have been increased in the last decades. In the present study, a total of twelve steel-concrete composite beam specimens separated into four groups using normal and high strength concrete, with and without fiber concrete were tested to failure using monotonic load. The test results show that the ultimate resistance increased by increasing compressive strength and/or adding steel fiber to concrete deck comparing with the normal concrete without steel fiber of about 1.4 to 27.1%, also using higher reinforced concrete with steel fiber would decrease deflection of about 9.3 to 29.5% and decrease slip of about 18.8 to 89.1%. A FRP strip, placed in longitudinal and transverse directions and injecting using Epoxy resin are used in treating the tested specimens. The specimens are then retested and the resulting ultimate resistance, deflection and slip are compared with the original test results to investigate the efficiency of each treatment method. Treating using longitudinal FRP was given an ultimate resistance of about 93.8 to 100.5% of original test results, but using transverse FRP give ultimate resistance of about 84.4 to 95.5% of original test results, meanwhile using Epoxy resin give ultimate resistance of about 68.5 to 95.1% of original test results. It was shown that, treating gives lesser deflection and slip compared with the original results.
