Comfortable Evaluation of Bridge-Station Combined Large Span High Speed Railway Station under Crowd Loading
Focusing on the Zhengzhou East Railway Station, which is the larges railway staton in China at present and has the characteristics of bridge-station combined structure, the fine finite element model was established by considering the influence of second dead loads. The rational crowd loading models were also determined based on the testing results. The vibration responses of waiting room floor and business floor caused by crowd loading are calculated. The vibration comfort was evaluated by the code of ATC (1999). The calculation and analysis results showed that: (1) the vibration of waiting floor and business floor under crowd get up loading is small, which can satisfy the comfort demand; (2) the vibration of waiting floor and business floor under crowd walk loading is bigger because the frequency of crowd walk loading (2 Hz) is closer to the structure first natural frequency, which can satisfy the comfort demand basically and only some individual parts can not satisfy the comfort demand; (3) the vibration caused by crowd loading can not neglected for the large-span flexible structures.
