Several studies have shown that there is a debonding failure between GFRP-S and concrete. The research aimed at analyzing effectiveness of GFRP-S bonding capacity on the reinforced concrete beams submersed in the sea water within a period of one year. The testing method used a monotonic loading with two point loads at the constant ramp actuator speed 0.05 mm/sc until the beam underwent the failure. In which method the beams were flexural tested on two simple restraints until beams underwent the failure. The testing was carried out with the total of two specimens concrete beams with 15 cm x 20 cm x 330 cm dimensions which were submersed in the sea water of simulation pool for 1 year with the concrete quality f’c 25 MPa. Strengthening of GFRP-S coated on the tensile area of concrete beams with 15 cm x 280 cm dimensions to compare flexural concrete beams capacity. As for the observed data during testing include load crack, ultimate load, deflection, and failure modes. The research results indicates that as the ultimate loading beams and GFRP-S bonding capacity on the beams submersed in the sea is smaller than the beams submersed in the simulation pool. The decrease of the load capacity of the GFRP-S beams submersed in the sea water for 6 months and 12 months, the bonding effectiveness of GFRP-S beams submersed also decreases as much as 7.37%, and 7.64% on the bonding effectiveness of GFRP-S which are not submersed. Failure mode that occurs is a debonding failure between GFRP-S and concrete.
