摘　　要：大跨度钢筋混凝土楼盖多用于公共建筑中,一般具有隔墙少、刚度小、阻尼小及柔性大等特点。当在其上进行有节奏运动时,容易引发楼盖的竖向振动舒适度问题,造成人员不适。利用国内新近研究成果,采用动力时程的分析方法对两个实际工程中不同使用功能的大跨度钢筋混凝土楼盖舒适度问题进行了详细的分析,结果表明楼盖体系具有适宜的舒适度。分析结果可为大跨度楼盖舒适度的时程分析方法提供案例参考。Long-span reinforced concrete floor is often used in public buildings,which has the characteristics of fewer partition walls,small stiffness,small damping and flexibility.Vertical vibration problems may occur at the floor system when the rhythmic movement is carried out on it,which in turn make the person uncomfortable.Based on the recent research results in China,detailed analysis of the comfort degree of long-span reinforced concrete floor with different functions in two practical projects was carried out by using the dynamic time history analysis method.The results show that the suitable comfort are provided by the floor system which is adopted in design.The results of this paper can provide a case reference for the time history analysis of long-span floor comfort.
