在當代製程技術與新材料的索引中，認為拱形建造尙未被探索完畢， 並以此前提進行以下研究探討。 本次主要有五個階段進行設計介紹:
1.拱頂傑作啟發與精神: 17世紀錘鍊式找形方法；19世紀初建築師高第的應用；2016年維尼斯雙年展的作品發表。
2.當代數位設計的多種建造方法: 1.Masonry；2.Tessellation；3.Reciprocal；4.Bending；5.Grid shell。
3.自主拱頂的數位技術介入與製造: 1.產出合理的應力結構；2.複雜曲 面有效的拆分與放樣時的精準定位；3.可預測的建造模擬。
4.實體網狀假設工程建造: 應用可塑及輕質材料(玻璃纖維管)與3D列印 接頭進行組裝；實際基地基礎的放樣與組裝；可塑網狀結構的成形機 制與製造工法。
5.成形架構與核心價値: ＦＲＰ工法應用於網狀假設工程的拱頂建造價 値。 當代拱頂建造上層以澆灌水泥為主形成完整的應力結構，當中的傳統 建造架構會使用到需拆卸的假設工程(Falsework)以及模具(Frame work)。
藉由可塑網狀假設工程之建造，當中透過現代化數位技術介 入，可以達到放樣高度準確性、製造更複雜的曲面型態。
應用此建造 工法可逐漸離開傳統的拱頂建造方法，當中的建造價値；
1.不需使用傳統模板工法；
2.通過平面放樣準確的曲面成形；
3.拆模後可重複製作；
4.此方法將可發展更大尺度的拱頂建造；
5.假設工程可以與上部結構一體成形增加結構的強度。
In the index of contemporary process technology and new materials,it is considered that Vaulting Construction has not yet been full explored, and based on this premise, the following research is conducted.
The project explores the ability of bending-active Gridshell structures, made in this case by fiberglass rebar, to produce an efficient structural framework for a fabric formed FRP shell.
The organizing pattern of the bars are guided by the TNA Grid of the structure,which help to shape the fabric formed FRP shell in relation to those optimal stresses.
The aim of this project is to expand a tectonic and methodological approach to developing structurally efficient, formally unique and buildable bending active frames and shell struc tures by working directly with force flow and material behaviour.
By adopting this manufacturing process and technology, it can be turned to Falsework and framework under construc tion in the future Architecture.
Today's digital design and manufacturing allows designers to lift many technical restrictions, which will allow architects to construct more autonomously.
