Correlation analysis of wind characteristic and wind-induced response of CITIC Plaza

This paper presented the analysis results based on the field measurement data of wind velocity and acceleration of main tower in CITIC Plaza during Typhoon Damrey.The results revealed that turbulence intensity of Typhoon Damrey was larger than the normal,and the across-wind dynamic response of CITIC Plaza approached the along-wind dynamic response under Typhoon Damrey.Meanwhile,the correlation of wind characteristic and wind-induced structure vibrations was investigated in selected different time intervals.The research indicated that 3-minute mean wind speed was reasonable in calculating the wind load and the wind-induced response.
