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.]]>ACI,2011Pages: 509Pages: 509AISC,19942nd Edn.,Aitcin, P.C. and P.K. Mehta,199087103107Arifovic, F. and B.
