Review on Seismic Isolation Technology Application and Research Status in Railway Station Buildings

In order to reduce the damage of railway station buildings under severe earthquakes and promote the widespread application of seismic isolation technology, the systematic review on the application and research status of seismic isolation technology in railway station buildings is presented from the perspective of universal applicability. The 9 types and typical examples of station buildings were sorted out according to different location relationships among station buildings, lines and squares. And such structural characteristics of station buildings were generalized as complex plane layout, more interlayers and staggered layers, large size of column grid, partial discontinuity of floor slab and uneven distribution of vertical stiffness. According to the scale of railway station buildings, the natural vibration periods of 27 typical railway station buildings in China were counted including small, medium, large and extra-large station buildings. It was found that the first three-order natural vibration periods gradually increased with the increase of the station building scale. By analyzing the engineering cases of the seismic isolation technology applied in station buildings at home and abroad, the main types and layout positions of seismic isolation components in railway station buildings were proposed. The challenges faced in the application of seismic isolation technology in railway station buildings were discussed from 5 aspects: the performance of the seismic isolation devices in high intensity cold regions, the seismic isolation technology in near-fault regions, the compilation of seismic isolation design standard, the maintenance and management methods for seismic isolation, and the evaluation for the seismic isolation resilience of railway station buildings. Such suggestions were put forward as developing the seismic isolation devices at low temperature, studying the seismic isolation design method for station buildings in near-fault regions, and standardizing the compilation of seismic isolation design, maintenance and management methods and the resilience evaluation for station buildings. It was expected to provide a reference for the further promotion of seismic isolation technology in railway station buildings. © 2022, Editorial Department of China Railway Science.
