    Abstract: 本研究結合電腦輔助設計軟體與數位設計製造工具,嘗試以新的方法發展傳統穹頂結構的形態,以發現不同於以往穹頂形態的可能。初步研究階段包括穹頂類型分析與數位設計製造兩個部分,首先透過平面線圖的繪製與分析將穹頂類型分為:單元、亂數、同心圓與放射狀等四種,並將其以旋轉、複製、變形、與改變密度等手法,衍生出64種穹頂的原型做為之後設計的參考。並且進一步將平面圖形轉換到立面與透視角度操作圖示,做為下一階段的穹頂類型發展的依據。

    第二部分的設計操作主要著重於穹頂外型的變形,將原來半橢圓形的穹頂外型做一系列的變化,進而分割變形穹頂,與第一部分的設計結果相呼應。在論文前半部討論穹頂的類型與變化之後,開始將不同的穹頂原型轉化成真實空間,分別設計出四種類型不同的穹頂結構,並且加入空間機能需求的想像。

    數位設計與製造對於是本研究的主軸,包括如何將傳統的結構行為、材料、與建築外形轉換為參數,並導入參數化設計中;所以在第四章中,嘗試發展出一套以參數化設計工具Grasshopper所建構的的參數化結構系統。在這個系統中只要輸入所想要設計的穹頂外形,經過元件的運算後,即可產生出三種不同的形態:三角面,三角洞面,與仿生物外殼面。

    在每一種形態中,適度調整內部元件的參數,即可以產生不同的結構與表面。也因為這個系統的完成,對於以往建築設計的思考方式開始有了不同的思維—簡單的外型,可以在短時間內產生多種不同變化,同時將模型切割圖製作出來。最後希望透過本研究的整理,能激發後續研究者未來對於穹頂數位設計與其他數位建築空間設計的突破與想像。
    This study discusses how to apply the computer software and digital technologies combined with the traditional typology of the parameterized dome. The analysis of dome typology and digital fabrication is summarized into two parts. At the beginning of the study, through the performance of the surface diagrams, different types of the dome are classified into unit, random number, concentric and radiated. We can then modify the dome structures by rotating, copying, deformation and density resulting in 64 different kinds of dome types which leads to more discussion. The next step is transforming the surface drawings into 3-dimension and the perspectives to be the reference for the more detailed analysis.

    The second phase of the study is deforming semi-elliptical dome shapes into a series of different modifications. And then to split the deformed dome and compared with the first part of the study. In the second phase of the study, the transformations of different types of dome are discussed, and then the domes are simulated in the real scale. Four different types of dome structure are designed and the functional needs are assigned accordingly.

    Digital design and fabrication are very important for this study. This research explores how to transform the traditional structure behaviours, materials and the architectural features into parameters, and also designing with these parameters. At the end of Chapter 4, a structure system is generated by Grasshopper. In the structural system, after inputs the parameters of dome shapes, three different kinds of domes are generated. The types of dome are triangular, triangular-hole surface and imitated biological-shell surface.

    After adjusting the parameters of the inner components in Grasshopper, different effects will be generated. The system designed is a bit of different from the traditional architectural design system -- with the same initial shape of a dome skin, the varieties of different structures will be computed in a short time, and the working drawings of dome are preceded. This thesis anticipates revealing the possibilities of applying digital design and fabrication of dome structural design in the near future.
