[摘要]对某客运站大跨度预应力混凝土楼盖结构进行路面不平整度仿真分析、动力特性的现场实测和有限元软件时程分析,采用基于信号检测理论的烦恼率舒适度评价方法计算楼盖的舒适度,并研究不同车辆荷载等因素对楼盖舒适度的影响。由测试和有限元分析可得,最大计权均方根加速度和加速度极限值均满足ISO规范对舒适度的要求。[关键词]客运站; 大跨度楼盖; 舒适度; 烦恼率中图分类号:TU93+1, TV32+3 文献标识码:A 文章编号:1002-848X(2015)17-0040-04

The comfort degree evaluation method of annoyance rate based on the signal detection theory was used to calculate the floor comfort degree, and the influences of different vehicle loads and other factors on the floor comfort degree were studied. According to the results of field measurement and the finite element analysis, the maximum weighted root mean square acceleration and acceleration limit value fulfill requirements of the ISO specification for comfort degree.Keywords:passenger station; large-span floor; comfort degree; annoyance rate
