Static, dynamic and aerodynamic effects of wind and the response of tall buildings can be mitigated and controlled using the architectural and structural strategies. Modifying the form and geometry, such as tapering, setback and aerodynamic form are considered architectural concepts; whereas, determining appropriate lateral-load based structural systems, such as tube systems, core-supported outrigger and diagrid systems are structural concepts. In this paper, a design method of tall buildings to consider the impact of the architectural and structural design strategies to reduce wind effect and control the response of tall buildings is presented. This method of design can also consider the interrelationship between form and geometry of tall buildings and structural systems by implementing a computational workbench for architectural parametric design module, Computational Fluid Dynamics (CFD), structural analysis program (ETABS) and also optimization procedure. The main objective of this innovative method is to create a comprehensive collaboration among architects, structural engineers, fluid and wind engineers in a non-linear back and forth process to find the most efficient geometry and form with minimum wind impact and also minimum weigh of the structure for a tall building.
