［摘要］   现行规范没有给出振动舒适度的具体评价标准及相应的设计参数。以青岛体育中心综合训练馆大跨度楼盖为背景，提出以3.3Hz 为下限控制频率作为方案选择依据。采用MIDAS/Gen 对9种不同结构方案进行有限元分析，结合其他评价标准，选取大跨度预应力楼盖进行结构设计。为了确保满足舒适度要求，对楼盖进行现场振动测试，试验结果与理论计算基本符合。实践表明，以频率作为振动舒适度设计的控制参数切实可行。

Abstract:The specific evaluation criteria of comfort and the corresponding design parameters are not specified in the current design codes. Based on the large-span floor of Qingdao Training Center, a lower limit control frequency of 3.3Hz was proposed as the basis for program selection. Finite element analysis results of nine different structural schemes were compared. Combined with other evaluation criteria, the large-span prestressed concrete floor was selected for structural design. To meet the requirements of vibration comfort, the onsite test was carried out, and the testing result is basically consistent with the theoretic analysis. It is proved that using the frequency as a control parameter for vibration comfort design is feasible.
Keywords:large-span floor; vertical vibration frequency; comfortable degree; finite element analysis; comprehensive comparison; dynamic parameters detection
