5. Conclusion The experimental investigation into the static and dynamic behavior of steel beams provided valuable insights into their structural performance, with the results validated through ANSYS simulations. The load-deflection behavior of all tested beams (ISMB 100, ISMB 125 and ISMB 200) showed a similar pattern under static loading. However, the stiffness increased with beam depth, with ISMB 200 exhibiting the highest stiffness, confirming the significant impact of cross-sectional properties on resistance to deformation. Under dynamic loading conditions, the beams displayed a similar load-deflection trend, but their natural frequencies varied. The frequencies were measured as 4.0 Hz for ISMB 200, 4.35 Hz for ISMB 125, and 5.29 Hz for ISMB 100, indicating that beams with lower stiffness tend to vibrate at higher frequencies due to reduced mass and rigidity. These findings highlight the differences between static and dynamic behavior, emphasizing the need to consider both loading conditions in structural analysis and design. The numerical simulations conducted in ANSYS closely aligned with the experimental data, confirming the accuracy of the finite element model in predicting structural response. Moreover, the damping characteristics of the beams suggest that energy dissipation primarily occurs through material yielding and structural vibrations, which must be considered in structures subjected to repeated impact loads. This study enhances the understanding of steel beam behavior under different loading conditions, contributing to the design and optimization of structural components for practical applications. The results highlight the importance of accounting for both static and dynamic loading effects in engineering design to ensure safety and durability. Future research can focus on complex loading scenarios and different material properties to further enhance structural performance predictions.
