Analisa Kapasitas Lentur Balok Hybrid yang Diperkuat Dengan GFRP Menggunakan Abaqus CAE

This study aims to analyze the flexural capacity of hybrid beams reinforced with Glass Fiber Reinforced Polymer (GFRP) Composite material through numerical simulations using ABAQUS CAE software. The modeled beams consist of two types, namely Control Beam and Beam reinforced with GFRP. Modeling is done by determining the physical and mechanical parameters of the material as well as static loading concentrated in the middle of the beam span. The simulation results show that the addition of GFRP provides a significant increase in the flexural capacity of the beam. Theoretically, the Control Beam has a flexural capacity of 26.47 kN, while the Beam reinforced with GFRP reaches 79.70 kN with an increase of 201.09%. The simulation also produces deflection and load data that are comparable to the experimental results and theoretical calculations. The maximum load value of the control beam simulation results of 25.10 kN compared to the theoretical results produces a deviation of 4.96% and the experimental results of 27.33 kN compared to the theoretical results produce a deviation of 3.36%, which is still within the tolerance limit of <10% for structural analysis. Thus, the simulation using ABAQUS CAE can be said to be quite accurate and valid as a reference in improving the structural performance of the beam, especially against bending forces
