Analisa Perkuatan Lentur Balok Hybrid Baja Ringan Paska Korosi Menggunakan ABAQUS CAE

This thesis examines the flexural strengthening analysis of hybrid lightweight steel beams after corrosion using ABAQUS CAE software. The study aims to model hybrid beams, determine their flexural capacity, and analyze the comparison between hybrid lightweight steel beams without corrosion and after corrosion. The results show that ABAQUS CAE is capable of predicting the behavior of hybrid beams, although there are differences between simulation results, theoretical calculations, and experimental data. For beams without corrosion, the simulation results showed a load of 48.7 kN with a deflection of 6.84 mm, the theoretical calculation yielded a load of 40.87 kN with a deflection of 0.371 mm, and the experimental results showed a load of 80.3 kN with a deflection of 17.9 mm. For beams after corrosion, the simulation results yielded a load of 42.6 kN with a deflection of 6.71 mm, the theoretical calculation gave a load of 55.89 kN with a deflection of 0.320 mm, and the experimental results produced a load of 77.1 kN with a deflection of 10.3 mm. The differences were due to model simplifications, assumptions in theoretical calculations, and variations in experimental conditions, as simulation is a model of reality that uses many simplifications and assumptions. This study suggests improving the accuracy of the model by considering more detailed factors and conducting comprehensive experimental validation for future research.
