高层建筑最大顶层加速度回归分析

摘要

The author performed the dynamic characteristic test of 9 high-rise buildings on the site by using SVSA ( The System of Vibration Signal Acquisition and Analysis). The maximum acceleration on the top storey is analyzed on the basis of the statistical data. Some useful engineering design relationship, the maximum acceleration on the top storey versus building storeys can be established by previous regressive analysis.%利用SVSA结构振动信号采集分析系统,对9幢高层建筑顶层最大加速度进行了现场实测,统计分析了结构在风荷载作用下的最大顶层加速度规律.回归得到了最大顶层加速度与房屋层数、自振周期之间的关系,可供工程设计参考.
