［摘要］介绍了在26m跨钢桥上进行的楼板振动舒适度试验。实测了单人行走、小组行走、人群行走等工况下楼板的振动响应，将单人行走工况的实测数据与有限元分析及AISC-DG11的计算方法做了比较。观测结果证实了步行力具有随机性；小组自由行走工况下楼板的响应一般不大于单人行走工况；人群行走工况的等效响应系数远小于1。最后给出了选择舒适度计算工况的设计建议。

Abstract:An in-situ test for floor serviceability of a 26m-span steel bridge under walking loads was introduced. The floor vibration response was measured under single pedestrian walking, group walking and crowd walking working conditions. The measured-data of single pedestrian working condition was compared with computing results by finite elements analysis and AISC-DG11 method. The test results show that walking force is non-periodic; floor vibration response undergroup free walking working condition is not larger than response under single pedestrian walking working condition; crowd walking equivalent response coefficient is far more less than 1. Finally the design advice for selection of floor serviceabilitycalculation working condition was provided.

Keywords:floor serviceability; in situ test; walking force; FE analysis; working condition selection
