Description:
The 76-story 306 m tall benchmark building chosen as the prototype structure for this study. The buildinga??s plan view is approximately 42 m square with two 7 m chamfers on opposite corners. To determine wind forces on the complex facade of the structure, a scaled model is studied in the wind tunnel. The wind tunnel tests were performed in the Department of Civil Engineering, at the University of Sydney.
In order to use wind tunnel results to determine wind forces acting on the full-scale structure, the wind generated by the wind tunnel must be adequately modeled. The parameters such as window velocity profile, intensity etc. are kept as constant as possible between the natural wind and the wind tunnel.
To relate wind tunnel pressure measurements to full-scale values, length scale is chosen as 1:400. The velocity scale between the wind speed in the tunnel and full-scale winds is approximately 1:3. With a time scale of approximately 1:133, 27s of wind tunnel data is recorded, extrapolating to an hour of prototype data.
