Modifying Tall Building Form To Reduce the Along-Wind Effect

In order to reduce undesirable wind effects and structural responses in tall buildings, there are two main solutions: architectural and structural. Architects can mitigate the wind effect on tall buildings by designing the form aerodynamically, or at least by using tapering and setbacks. Structural engineers can reduce wind effects by choosing and designing efficient structural systems, such as the tube and diagrid systems. This research introduces an alternate design method, by creating an innovative computational workbench to design efficient tall buildings to withstand and adapt to the along-wind effect. An architectural parametric design procedure in AutoLisp (AutoCAD) generates the models, and is connected with a Computational Fluid Dynamics (CFD) program (ANSYS) and a structural analysis program (SAP2000).
