Influence of Turbulence, Orientation, and Site Configuration on the Response of Buildings to Extreme Wind

Figure 6

Mean displacement response of the top corner of the building under different flow conditions and site configurations: (a) -direction; (b) -direction. Mean responses in the -direction are larger than those in the -direction because of the geometry (different projected areas in the two directions). The sheltering effect from a high-rise building in the upstream flow resulted in a reduced mean displacement response ( -direction at 90° with configuration II). The turbulence intensity does not significantly influence the mean values of the displacement response when the high frequency parts of the wind spectra are matching (configurations I, II, BLa, and BLb as shown in Figure 3). However, the along-wind response in the -direction under smooth flow (SF) is relatively reduced due to the lack of high-frequency turbulence.
