GPS监测高层建筑风致振动变形及小波应用

Measurement of Wind-Induced Vibration of Tall Buildings Using GPS and Wavelet Application

  • 摘要: 从模拟振动实验和工程实测两方面验证了高采样率GPS单历元定位技术是一种监测高层建筑风致振动的有效手段。应用小波对GPS观测的振动信号进行提取,结果表明,GPS能精确地观测到建筑物2mm的风致振动变形。

     

    Abstract: Tall buildings are very sensitive to wind. We demonstrate that high-rate GPS single epoch positioning technology is effective in measuring wind-induced vibration of tall buildings by analyzing simulation vibration test and field measurement data. After application of wavelet decomposition and reconstruction, 2-mm vibration deformation of tall buildings can be extracted precisely from the GPS time history solution.
