摘要
以某学校风雨操场屋顶为研究对象,采用MIDAS/Gen软件进行动力时程分析,研究大跨度钢筋混凝土楼盖在有节奏运动荷载作用下的动力响应特性,分析结构阻尼比、梁高、板厚、附加荷载、荷载分布形式和荷载类型等因素对大跨度钢筋混凝土楼盖结构振动响应的影响。结果表明,增大阻尼比、梁高、板厚和附加荷载,可以减小大跨度钢筋混凝土楼盖的振动响应。
Vibration response of the large span RC floor of a school wind and rain playground was studied under the rhythmic activity loads.Dynamic time-historical analysis was carried out by MIDAS/Gen software.The influence of different factors on vibration response of the large span RC floor was studied,such as damping ratio,height of beam,thickness of floor,additional load.The results show that increasing the damping ratio,height of beam,thickness of floor and additional load can reduce the vibration response of the large span RC floor.
