Statistic and modal analysis of the Krk bridge utilizing ANSYS

Abstract. Connecting mainland Croatia and the island of Krk, Krk Bridge lies upon the Krk Channel of the Adriatic Sea. The bridge is one of the longest arch bridges and was the longest when it was built worldwide. However, considering the harsh environment in which the bridge is located, the slender structure of the bridge has raised concerns about the system's stability. However, with the most widely investigated studies focusing on the corrosion impact on the material and finish of the bridge from the harsh environment, there remains largely unexamined structural analysis to be done. Hence, this study seeks to use ANSYS and Workbench to investigate the reliability of Krk Bridge concerning statistical structure and modal analysis to offer insights into the future maintenance and reinforcement of the bridge itself, as well as provide a reference for other infrastructural bridge projects in the future.
