Currently, there is concrete reinforcement engineering using reinforcement other than steel reinforcement. One of them is by using glass fiber-reinforced polymer (GFRP), which has five times steel rebar tensile strength. This research aims to compare two designs of a 12 stories bulding using steel reinforcement and GFRP reinforcement. Main focus of this research is comparison of concrete and rebar material cost from both designs. In steel reinforced concrete design, the code to be used is SNI 2847:2019, meanwhile in GFRP reinforced concrete design, the code to be used is ACI 440.11-22. There is a difference in mechanical behavior between steel rebar and GFRP rebar. Steel rebar will experience yielding after reaching its ultimate stress, meanwhile GFRP rebar will immediately fail after reaching its ultimate stress. Besides that, GFRP rebar will be neglected if located in compressive cross section because of its low compressive modulus. The result shows that material cost on GFRP reinforced design is higher compared to steel reinforced design. Material cost is higher on GFRP reinforced design because GFRP rebar price is nine times higher than price of steel rebar price.
