In this paper,the characteristics of structural response and modal parameters of Shenzhen New World Center (height 238 m) are analyzed based on the field data during five typhoons in the last 10 years. The field results are further compared with the wind tunnel test results when the roughness exponent α is 0.22,0.30 and 0.35 respectively. The field results show that the building exhibits obvious crosswind vibration when reaching its maximum vibration amplitude,and the corresponding vibration is in the north-south direction. The measured maximum acceleration is 17.28 cm/s2,which meets the requirement of residential comfort. During the five typhoons,the modal frequencies are shown to be evidently amplitude dependent and time-varying,and it is more reasonable to describe the variation of modal frequency with time than the variation with amplitude. The modal frequency first decreases with time and reaches its minimum at the peak wind speed,and then returns to the normal value. The modal damping ratios tend to be scattered in the middle- and low-amplitude region,and rise slightly with increase in the amplitude. The maximum damping ratios in the alongwind and crosswind directions are 1.9% and 1.2%,respectively. The wind tunnel test results for α=0.35 are in good agreement with the field measured results,indicating that the wind tunnel test results for terrain category C are conservative.
