| Abstract |
In this study, the wind pressure was measured using multiple pressure measuring systems for high-rise buildings with modified edges. The
pressure patterns that could occur on the surface of high-rise buildings were investigated through Independent Component Analysis (ICA). The
power spectrum density was then evaluated using each mode obtained through the ICA. In the first mode of the ICA, it is possible to
identify the shear layer caused by the blowing up. Even if the high-rise building was facing towards the direction of the wind, negative
pressure were identified on the corner surfaces of the high-rise building. In the second mode of the ICA, it is identified that the vortex
appears to be stronger on the wind-facing edge surface. Furthermore, power spectrum densities were also used to identify the vortex
phenomena occurring in secondary mode of the ICA. |
