## 2 Testing the Cho'ponota L1 Bridge
### Static Vehicle Loading Test  
Static vehicle load tests are one of the most commonly used methods for evaluating the structural performance of bridges and verifying the accuracy of their design. These tests provide an opportunity to directly observe the behavior of the structure under controlled loads applied to the bridge. One of the most significant advantages of static load tests is their ability to reliably assess whether parameters, such as stresses and displacements experienced by bridge elements, remain within the design-specified limits. Additionally, the data obtained during these tests serve as a fundamental dataset for the update of finite-element models of bridges, enabling more accurate simulations to be performed. Before starting the static vehicle load tests on the Cho'ponota L1 Bridge, the displacement values of the bridge were obtained based on the local coordinates of the marked points on the underside of the deck (Table 3). The displacement values provided in Table 3 are important as they will serve as a reference source for potential experimental test studies on bridges in the coming years. Following this preliminary work, a total of 28 different loading scenarios were conducted as part of the static vehicle load tests on the three spans of the bridge using trucks weighing 30 tons and 50 tons. These loading scenarios were carefully planned to identify the displacement values that could occur in various parts of the bridge. Additionally, evaluating the effects of trucks with different weights at different locations allows for the simulation of possible conditions the bridge may encounter throughout its service life. In the test procedure, after positioning the trucks at the designated locations on each span, a waiting period of at least 15 min was observed before starting the test. This waiting time was necessary to ensure that the dynamic stress fluctuations caused by the truck's movement as it approached the designated region of the bridge completely dissipated. For each loading scenario, geodetic displacement values were recorded at designated points on the bridge using the total station. Some images from the static vehicle load tests conducted on the bridge are presented in Figure 6. The displacement values obtained from the static load tests on the Cho'ponota L1 Bridge are presented in Table 4. \begin{table}

Table 2: _Cont._When examining the values recorded at different locations and loading scenarios for each span, it was observed that span S2 exhibited higher displacement values compared to the other spans. During the construction phase, periodic measurements also indicated displacement values exceeding the expected limits. Considering this issue, the 100-ton truck, which was used in the design phase, was not utilized in the tests to avoid any potential
