Paragraph starter

Research into ice-induced vibrations on structures, such as bridges in cold regions, highlights the critical role of fluid-solid coupling. Studies indicate that the interaction between water flow and ice during impact significantly alters vibration dynamics, often leading to an extended vibration period and a reduction in peak impact forces (Zhang et al., 2024). This suggests that designs must account for these complex environmental interactions to ensure structural integrity and safety.
