Abstract: To meet architect's requirements of comparing different facade shapes of Beijing CBD Core Area Z15 polt China Zun Tower  and engineer's requirements of optimizing structural performance, structural parametric design was introduced into this project. The geometric design software Rhinoceros and its parametric design plugin Grasshopper were used to define the geometry of the structural system and establish geometric models under different architecture conditions. Then by Arup in-house developed design tools, the structural information such as section, material and loading were embedded with geometric elements of Rhinoceros and exported into commercial software like GSA, ETABS and SAP2000 to create complete structural analysis models automatically. These achievements could be used for the information share with architects and MEP engineers, CAD drawings production, finite element detail analysis and BIM model, which achieved structural performance optimization in short time and improved the whole design efficiency significantly.

Keywords:China Zun Tower; super highrise building; structural parametric design; structural optimization; structural design
