This study comprehensively compares dynamic and static forces in reinforced concrete (RC) beams, utilising experimental and finite element analysis (FEA) methodologies. Experimental tests involve monotonic two-point loading of 1 m x 150 mm x 150 mm RC beams using a universal testing machine (UTM). Deflection measurements are taken at three distinct locations (S1–S3) using various sensors, including force resisting sensor (FRS), flex sensor (FLS), MEMS accelerometer, and Piezoelectric sensors. The experimental data is then compared with FEA results obtained through ANSYS 16.0 software. Additionally, dynamic analysis is conducted, and results are presented in 3D graphical format. Mode shapes and harmonic responses are analysed. The study further discusses the sensor outcomes that align closely with FEA results. Overall, this research provides valuable insights into the dynamic and static behaviour of RC beams and offers a robust validation approach through experimental and computational analyses. © 2025 Elsevier B.V., All rights reserved.
