MPa to 41.72 MPa. Overall, the NDT test outcomes suggest that the bridges are structurally sound and capable of withstanding the required loads. By conducting a comparative analysis of OMA with numerical results, it has been observed that the natural frequencies of the mentioned bridges exhibit a strong correlation. Furthermore, the static analysis in the numerical twin has revealed that all the bridges remain within acceptable limits for the increased axial loads. Higher differences in frequencies of numerical and field study might be due to the boundary conditions. References Agrawal, A., & Chakraborty, S. (2019).
