The effectiveness of a new developed fiber-steel composite plate designed specifically to be used for strengthening of reinforced concrete slabs has been experimentally investigated. Nine reinforced concrete slabs were constructed and tested. Four of the slabs were strengthened with carbon fiber-steel composite plate (CSP), four of the slabs were strengthened with glass fiber-steel composite plate (GSP), one slab was used as a control specimen. The experimental results showed that new strengthening system controlled premature debonding and provided a more ductile failure mode than other conventional FRP strengthening systems. The observed deformability were 3.55~4.69 and 3.1~5.5 for strengthened slab with CSP and GSP, respectively. In addition, maximum load was increased by 75.6% and 90.9% for strengthened slab with CSP and GSP, respectively, comparing with control slab.
