Abstract

: Columns are structural elements that transfer axial loads to the foundation, so the type of reinforcement used strongly determines structural performance. Conventional steel reinforcement is susceptible to corrosion, especially in aggressive environments. Glass Fiber Reinforced Polymer (GFRP) is an alternative because it is corrosion resistant. However, research that directly compares it with steel under the same testing conditions in Indonesia remains limited. This study aims to determine and compare the axial compressive strength of concrete columns reinforced with BJTS-42 steel and concrete columns reinforced with GFRP as the main reinforcement. The study was conducted experimentally at the laboratory of PT. Kembar Jaya Mandiri Mulya, Demak. The test specimens were cylindrical columns measuring 150 mm × 300 mm with a design concrete strength (fc’) of 25 MPa. The main reinforcement consisted of D10 deformed steel bars and D10 GFRP bars. Compressive strength tests were carried out at 14, 21, and 28 days, with normal concrete cylinders used as quality control. The test results were also compared with the theoretical nominal capacities based on SNI 2847:2019 for steel and ACI 440.11-22 for GFRP
