數位科技對於建築，不論是在設計或是製造，已產生革命性的影響。設計方面，參數化技術的導入，使得設計者能更快、更有效率且更精準的設計出更為複雜的曲面造型；製造上數位生產技術的進步，則讓曲面造型構築能更易實現。近年台灣也逐漸搭上這股數位建築潮流，不過，主要仍著重在數位造型方面，較欠缺從設計到構築階段，如何應用數位科技做串連的研究和實踐，使得數位設計與本土營造技術無法銜接。因此，本研究擬以可拆解曲面構造為例，探討如何應用數位科技來構築曲面構造。
本研究採用了「案例導向式設計法」尋找可供參考之設計經驗，作為造型上之依據。於擬定設計目標與邊際條件後，本文選擇加州科博館為可拆解曲面構造設計發展之起始案例，利用兩向工字樑構築曲面，並發展讓樑隨曲面旋轉，使樑能更貼近設計之曲面。接著以蒐集彙整之相關案例，尋找拆解工字樑之方式，經過縮尺模型施作後，逐步修正起始案例。在多次修改及模型施作後，完成最後之設計。
過程中，本研究導入Rhino-Grasshopper作為參數化設計工具，讓構成曲面之工字樑各構件，皆能以平面方式生產，並利用榫接構法，作為各構件之接合方式，將傳統構法與現代設計工具做一重新結合，發展一種不同以往之可拆解曲面構法。
為模擬實際應用之可行性，且秉持著自力造屋的精神，本研究以瓦楞紙為材，藉由雷射切割機裁切製造，多次進行縮尺及足尺模型施作，以針對缺點進行檢討與修正。藉由完整的設計到製造過程，實際體驗數位構築的方法與程序。
研究成果顯示: 應用參數化軟體作為數位構築工具，除了成功突破以往的設計效率，以及製造上難以大量客製化的侷限外，參數化軟體與傳統構法結合後，進而能發展出有別以往的構築方式。以參數化軟體作為聯貫設計到製造的媒介，更能有效地整合設計、結構、 管理及數位生產等各相關領域技術。研究過程中所獲得之經驗，也可供後續之本土數位建築研究參考。

With the improvement of digital technology, it has a revolutionary impact for architecture whether in the respect of design or manufacture. In the part of design, the designers can build more complicated curved-surface form more quickly, efficiently and accurately by the parametric technique imported. The improvement of digital produced technique makes the curved-surface construct easier. Recently, the digital architecture is getting popular in Taiwan; however, it mainly focuses on digital forms but lacks the discussion of applied digital technology from designing to constructing, and leading to the design can’t combine with local construct technique. Therefore, the study takes demountable curved-surface structure for example to explore the digital technology how to build the curved-surface structure.
A "Case Based Design" method is used for finding referable experience as a basis of form. After establishing the design objectives and requirements, California Academy of Sciences which constructs the surface by the I-beam is selected as the initial case to design the demountable curved-surface structure. The study develops and makes the I-beam more close to the surface by rotating and further finds the ways to demountable I-beam by gathering, integrating related cases, and making reduced scaled models. Through various revising and modeling, the final design is completed.
In the process, the study uses Rhino-Grasshopper, a parametric design tool, to make all components of I-beam be manufactured in plane. Furthermore, components combine together by utilizing the design of joggled joint. Those combinations of traditional construction method and modern design tool develop as a demountable curved-surface construction method differently.
To simulate the feasibility of real-life applications and holding the spirit of building by ourselves, corrugated cardboard and a laser cutter for digital fabrication are used to make a reduced scaled model and a full scaled model. Based on the procedure, the study has reviews and revises until the design meets objectives and requirements. By the full process from designing to producing, it experiences practically the methods and procedures of digital construction.
Conclusively, the research reveals that by using a parametric program as a tool of digital construction, it not only improves successfully the efficiency of design and the limit of massive customization, but also creates the new construction method by combining with the traditional method. Utilizing the parametric tools from design to manufacture integrates efficiently the relative technique including design, structure, management, digital manufacture, etc. The experience mentioned from this study can be a reference for follow-up digital architecture researches.
