Propagation Law of Structural Vibration in Large Transportation Hub and Vibration/Seismic Isolation Measures

[Objective] Large-scale integrated transportation hub structure is a vital component in urban layout, characterized by significant investment, extensive construction scale, and diverse functionalities. Ensuring the resilience of such buildings to seismic forces, preventing damage while preserving functionality, and providing sufficient safety and comfort under the influence of complex multidimensional traffic are engineering challenges of practical significance. Thus, it is necessary to sort through and summarize relevant literature research on this subject. [Method] The environmental vibration issues caused by various traffic loads along routes and buildings are reviewed. Additionally, the research status of vibration/seismic isolation devices commonly used in transportation hub structures is explored. The research achievements of scholars in China and worldwide in vibration response measurement, vibration prediction simulation, and vibration propagation laws are summarized. Based on the limitations of exist
