Numerical Simulation of Three-Point Bending Test on Steel Fiber-Reinforced Concrete Specimens Using DIANA FEA

Resumo

This study presents a numerical investigation of the behavior of steel fiber-reinforced concrete specimens under three-point bending tests employing different model approaches. Steel fiber-reinforced concrete has gained significant attention in the construction industry due to its enhanced mechanical properties, including improved ductility and crack resistance. Understanding its behavior under loading conditions is crucial for optimizing structural design and ensuring durability. The simulations were conducted using DIANA Finite Element Analysis (FEA) software, and the comparative analysis was design to compare their effectiveness in predicting the structural response. The simulations were validated against experimental data from laboratory tests to ensure the accuracy and reliability of the numerical predictions. Through comparative analysis, this study evaluates the performance of each modeling approach in predicting key parameters such as load-displacement response, crack mouth opening and ultimate failure mode. Insights gained from these comparisons will provide valuable guidance for selecting the most appropriate modeling technique for similar structural analyses in practical engineering applications.
