In this study, on-site monitoring was used to obtain the temperature field distribution and cable force values of the bridge at various times, the temperature change pattern of the bridge elements, the temperature sensitivity of the cable force of different parts of the bridge, and the trend of the cable force under temperature load were all analyzed. The static response of the wires was studied under various operating circumstances. The total cable force of the bridge is inversely related to the temperature rise and fall, and the temperature sensitivity of the cable force in different parts of the bridge is different under the same temperature effect. The change in cable force is uneven. They vary according to the loading circumstances. This project's cable force changes are the most substantial and consistent with observed circumstances and should be appropriately considered in comparable projects. Thermal impacts must be addressed in strand cable safety design.
