Abstract: Background: Reinforced concrete cylindrical shell columns are extensively used in water infrastructure, industrial facilities, marine structures, and high-rise buildings due to their high load-carrying efficiency. However, under axial and dynamic loading, these structures are vulnerable to coupled vibration and buckling effects. Most existing studies examine modal characteristics and buckling behaviour separately, limiting understanding of their interaction. This study addresses this limitation by developing an integrated framework for simultaneous...
