摘　　要：针对大跨度钢-混凝土组合空腹楼板结构,首先采用模态参数识别方法对楼板进行动力特性参数识别,然后采用行走路线法对楼板开展人行走激励下的舒适度分析,并考虑了楼板结构跨高比、表层薄板厚度等参数对响应加速度的影响,最后实测工程中不同人行走激励工况下的加速度响应.分析表明,大跨度钢-混凝土组合空腹楼板具有较好的舒适度性能,结构参数对加速度响应有一定影响,各工况下的实测加速度峰值均满足规范要求.For long-span steel-concrete composite open-web sandwich plate,the modal parameter identification method is used to identify the dynamic characteristic parameters of the floor.Then the comfort analysis of the floor under walking excitation is carried out by using the walking route method,and the influences of span-depth ratio,plate thickness and other parameters on the response acceleration are considered.Finally,the acceleration response of the floor under different walking excitation conditions is measured.The analysis shows that the long-span steel-concrete composite open-web floor has good comfort performance,and the structural parameters have some influence on the acceleration response.The measured peak acceleration under each working condition meets the code requirements.
