| 摘 要： | 就各国建筑规范中关于舒适度指标的楼盖振动的基本规定和当前主要的楼盖振动模型进行了介绍。通过对某超高层大楼楼盖的现场振动测试，对脉动情况下楼盖阻尼比进行了分析，并将振动峰值加速度实测结果与理论计算值进行了比较分析，对不同楼盖振动加固方法的效果进行了比较讨论，最后总结了基于舒适度指标的楼板振动控制设计中存在的不足和需要进一步研究的内容。

| Abstract: | Tie comfort indices of floor slab vibration in several countries' building design codes and current popular vibration models are introduced in this paper.According to the testing results of floor slab vibration on a super high-rise structure,characteristic of floor damping ratio is analyzed,comparison between the calculation results and the test results of vertical maximum acceleration is conducted,and effects of several different reinforcementing methods carried on floor slab are comparatively discussed.Finally,conclusion is drawn on the weakness of current floor vibration-control design based on comfort index and the direction is shown for further research. |
