Field measurement and wind tunnel test of a long-term monitored super high-rise building under strong wind

Abstract
This paper employed the Bayesian spectral density approach (NewBSDA) that incorporates aerodynamic
characteristics to identify the dynamic parameters of the 280-meter Shenzhen Zhuoyue Century Center (ZCC) during
Typhoons Hato, Pakhar, and Mangkhut. Variations in modal frequencies and damping ratios were analyzed, and a
detailed comparison was made between field measurements and wind tunnel results to investigate the causes of
discrepancies.Results show that (1) The maximum peak acceleration under all three typhoons occurred in the north
south direction. During Typhoon Mangkhut, a peak acceleration of 23.9 milli-g was recorded—an exceptionally high
value rarely observed in field measurements of super high-rise buildings. (2) Modal frequencies decreased over time
but recovered after strong wind-induced vibrations. A multi-value pattern emerged in the frequency-amplitude
relationship during Typhoon Mangkhut. (3) Damping ratios were higher under strong winds compared to those in
breezy conditions. Their correlation with amplitude was weaker than their correlation with time. (4) Wind tunnel and
field measurement results showed good agreement when a broader range of real terrain conditions was considered.
This suggests that the upstream terrain roughness specified by the Chinese Code, as applied in prior wind tunnel tests,
tends to be conservative.
