Abstract

Concrete has a weakness, namely that it is not strong enough to withstand tensile forces, so the concrete can crack, break or crumble, so concrete repairsare needed using strengthening methods to overcome the damage. The strengthening method used is external restraint using Glass Fiber Reinforced Polymer (GFRP). The aim of the research is to determine the effect of strengthening external restraints on reinforced concrete beams that have been loaded using glass fiber reinforced polymer (GFRP) on bending moment strength.
The research consisted of testing the bending moment strength of corroded reinforced concrete beams. The test object is in the form of a block measuring 15x 15 x 60 cm with concrete quality fc 22.27 Mpa. Using GFRP Spacing Variations of O cm, 5 cm, 10 cm and GFRP Width of 5 cm, 7 cm, 9 cm. Bending moment strength testing is based on ASTM C28/C28M regarding standard test method for flexural strength of concrete (using simple beam with third-pointloading).
The results of the research are that strengthening external restraints using GFRP can increase the bending moment strength with the largest bending moment strength at O cm GFRP spacing variations of 5.10 kNm and at 9 cmGFRP width variations at 5. 60 kNm. Meanwhile, the spacing variations of 5 cm,JO cm and width variations of 5 cm, 7 cm are respectively 5.23 kNm, 4.67 kNmand 4.63 kNm, 4.90 kNm.
