The simultaneous field measurement on wind speed, wind direction and wind-induced acceleration response were conducted on the super tall building-Litong plaza in Guangzhou when typhoon Vicente affected this building. The wind filed characteristics atop of this building were obtained through statistical analysis. Meanwhile the frequency-spectrum characteristics of wind-induced response, the dynamics characteristic were identified from the measured wind-induced acceleration data. The nonlinear damping ratio was also obtained by the random decrement technique. On the other hand the displacements atop of the building were previously measured by GPS system under ambient condition. The multi-path effect of the measured displacement was investigated and its removing method was studied in this paper. The comparisons of the obtained natural frequencies from the different methods were conducted. The effectiveness of the identified natural frequencies was therefore verified by the compared results.
