This paper presents the experimental results for reinforcement effect for FRP strengthened steel structures. Bond behavior, flexural, and compression were conducted. First, from bond test, it was able to examine the interfacial behavior and to evaluate the interfacial bond stress between AFRP plate and steel plates. Second, for flexural test, maximum load was increased with increasing FRP layer. Also, debonding failure was observed between steel plates and FRP plates. Third, for compression, for short columns it was observed that two sides would typically buckle outward and the other sides would buckle inward. Also, for long columns, overall buckling observed. The maximum load was increased up to 33% for slender section short columns. From the test, it was able to verify the reinforcement effect for FRP strengthened steel structures.
