Issue Date: | 2024 | Publisher: | [Kalhat, Lebanon] : [University of Balamand], 2024 | Abstract: | With an emphasis on their effects on load-bearing capacity, displacement, and failure modes, this thesis examines how steel fiber dose and orientation affect the structural performance of concrete beams. Steel fiber-reinforced concrete (SFRC) beam behavior under varied loading circumstances is simulated numerically in this work utilizing Abaqus software and Finite Element Modeling (FEM). Steel fiber dosages of 0.25% and 0.5% were added to the concrete matrix in three different orientations: random, vertical, and horizontal. In order to validate the numerical models, the results were compared with experimental data, paying special attention to damage patterns, displacement (δmax), and maximum load (Pmax). According to the results, fiber dosage and orientation have a major impact on the mechanical characteristics of SFRC beams; better structural performance is associated with greater dosages and properly oriented fibers. By demonstrating how steel fiber reinforcement can improve the strength, ductility, and load-bearing capacity of concrete beams, this study provides important information for maximizing the use of SFRC in construction. |
