摘要 深圳火车北站为人群密集型大跨公共建筑,楼盖梁最大跨度43m。针对大跨度楼盖的振动舒适度问题,建立楼盖整体有限元模型,以IABSE建议的单人步行激励为基础,考虑行人起步相位的随机性,分别考虑了人跳跃、行走等最不利分析工况,通过多点输入时程分析方法求得结构的加速度响应,对深圳北站楼盖进行人行舒适度分析。并采用ATC给出的人行舒适度性能水准作为评价标准。计算结果表明深圳北站站房楼盖具有适宜的刚度和舒适度。所采用的计算方法及控制标准可作为类似工程参考。 Station building of Shenzhen North Station was a crowding long-span public building. The largest span of floor system beam was 43m. The vibration comfort of large-span floor system is studied. A finite element model of a large-span floor is established. Based on the single walking force of IABSE( International Association of Bridge and Structural Engineer),a method is proposed considering the random distribution of persona's initial phase angle. And people jumping and walking were considered as the most disadvantageous cases. Then the vibration comfort of the bridge is analyzed by a multi-support excitation and time history analysis method. The comfort performance level is given according to ATC( Applied Technology Council). The results show that the stiffness and comfort of station building floor system of Shenzhen North Station are suitable. The computing method adopted and evaluating standard could be considered as the reference for the similar projects.
