Details of Bridge 5's NDT test results are shown in Table 9. In the maximum tested regions of the RCC structure, concrete underwent the RH test, and the results showed that the concrete's quality fits into the good to very good category. Similar to this, the average quality grade of the concrete at the largest tested area of the RCC construction is good based on the UPV results. The concrete at the largest tested area of the RCC construction exhibits a 90% likelihood of no corrosion or Uncertainty based on Half Cell Potential findings. Finally, according to the findings of the concrete core tests, the RCC Pier wall of the bridge construction has an average compressive strength of 28.19 MPa. 4.2. Finite element Modal Analysis The computed fundamental frequencies are compared to the structure that really exists on the site to demonstrate the relationship between the numerical model created and that of existing structure. The frequencies obtained from the numerical modeling of bridge-1 are shown in fig. 12 (a). Bridge-1's static analysis is shown in fig. 12 (b). The frequencies identified by numerical analysis are shown in Table 8.
