青岛体育中心训练馆大跨楼盖人致振动实测与分析

在青岛体育中心训练馆大跨楼盖上安装了振动监测系统,监测楼盖在使用状态下的振动幅值并进行振动舒适度的评估。基于ANSYS通用有限元软件建立了该楼盖的分析模型,并施加单人及群体荷载,计算得到的响应与实测响应进行了比较,结果表明,该建模方法及荷载取值合理。

Field measurement and analysis of human-induced vibration of long-span floor in Qingdao Sport Center

A permanent vibration monitoring system has been designed and installed on the long-span floor of the Training Stadium in Qingdao Sport Center.The system monitors the vertical vibration of the floor under operational conditions,and the measurements from the system can be utilized for vibration serviceability assessment.Furthermore,the finite element model of the floor has been established via ANSYS as a platform.The vertical acceleration responses of the floor under people walking and jumping were calculated and compared with the measured values.The results suggest that the suggested modeling technology is applicable and the walking load model used is reasonable.
