［摘要］为满足建筑师对北京CBD核心区Z15地块中国尊大楼外形的多方案比选及工程师对结构性能优化的需要，在设计中引入了结构参数化设计。通过对塔楼整体结构体系几何逻辑的定义，结合参数化插件Grasshopper和图形软件Rhinoceros，实现了不同建筑条件下几何模型的自动化建立。再通过奥雅纳二次开发工具将构件截面尺寸、材料属性、荷载形式及大小等信息赋予图形软件Rhinoceros中的几何单元，并导入GSA，ETABS，SAP2000等软件中，生成计算分析模型。以上模型成果可进一步应用到与建筑和机电专业的信息共享、CAD出图、有限元节点分析和BIM设计之中，实现了短时间内结构性能的优化和整体工作效率的提高。

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.
