Modeling and Analysis of Reinforced Concrete Beam Using ANSYS Software

Understanding how structural elements such as beams, columns, and walls respond under loading is essential for designing efficient and safe structures. This article presents a study where a reinforced concrete beam is simulated and analyzed using Finite Element Analysis software, specifically ANSYS. The beam model, measuring 2100 × 200 × 100 mm, incorporates one 20 mm diameter bar for primary reinforcement, two 6 mm diameter bars as hanger bars, and 6 mm diameter bars spaced at 75 mm intervals for shear reinforcement. The behavior of the analyzed beam is assessed in terms of flexural behavior, crack formation, and displacement under various loading conditions ranging from 10.8 kN to failure load (36 kN). The analysis reveals that the results are highly influenced by factors such as mesh density, material properties, and load increments. Methodology of work. As a basis for the comparative analysis, 5 experimental samples of reinforced concrete beams were taken and their research results were processed. For the next stage, similar reinforced concrete beams were modeled in the ANSYS computer in a non-linear setting using FE elements SOLID65 and Link 180. Results. The optimal version of the calculation scheme was proposed, and after the calculation, graphical dependences of the stress-strain of the samples under the action of the load were created.
