| 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. |

| Keywords: | GPS single epoch positioning tall buildings vibration measurement wavelet |
