摘要
High-Frequency-Pressure-Integration tests were carried out in a wind tunnel to investigate wind load characteristics of the tapered super-tall buildings using rigid models. Test results show that a tapered super-tall building might spread the vortex-shedding over a broad range of frequencies and make more effective for reducing vortex-induced vibration in across-wind direction. With increasing of taper ratio, the normalized power spectra and the RMS of lift coefficient decreases, power spectra band width of lift coefficient increases, but drag and torsion coefficient almost keep the same.
