Vibration-seismic dual control design of overnight passenger accommodation of Hefei Xinqiao International Airport
The basic structural system of the overnight passenger accommodation of Hefei Xinqiao International Airport and its relationship with the underground rail transit structure were introduced.The floor vibration of the overnight passenger accommodation under uncontrolled and controlled conditions was evaluated,and it was determined that vibration isolation is required.The basic design ideas of vibration-seismic dual control,the arrangement process of vibration isolation supports,and the design concept of limiting device were discussed,and the seismic performance of the structure under vibration-isolation conditions was analyzed.The results show that after the steel-spring isolators and limiting devices are used,the structure meets the requirements of the code for vibration and secondary radiated noise.At the same time,the seismic performance of the structure under vibration-isolation conditions can be guaranteed,thereby achieving the dual control of vibration and seismic.
