環境永續是當代社會刻不容緩之課題，廢棄物減量為當務之急，輕量化結構因而被廣泛研究，氣候之極端變化也讓降低碳排量、使用綠色建材成為未來趨勢。本研究以竹材做為構築材料，配合薄膜式完全張力體結構系統，發展可進入使用之結構空間。竹材在台灣分佈面積廣，生長期短，砍伐種植生長循環速度快，對環境衝擊較小，為利用性極高之在地環保建材，完全張力體系統中，桿件受純軸壓力及純軸拉力，斷面得以非常經濟，是一種力學行為本質上輕量化的系統。
本研究先針對所使用之材料進行材料試驗，針對小直徑的箭竹及桂竹進行竹材抗壓試驗及挫屈試驗，與尤拉公式計算之理論臨界挫屈載重比較，發現尤拉公式對於細長比大之竹材，臨界挫屈強度有低估趨勢，又針對無彈性防水薄膜進行不同角度抗拉試驗，薄膜於平行及垂直布邊方向、及45度方向具有較大之極限抗拉強度，判斷與斷面受力是否平均有關。接著分別以彈性薄膜與無彈性薄膜為材料，發展完全張力體之空間設計，並詳細闡述完全張力體之系統定義、力學特性及穩定性質，針對旋轉多邊形柱體及壓桿交錯曲面系統進行幾何分析、預力分析、內力分析及受力行為探討，將旋轉多邊形柱體形狀及內力分析結果，與SAP2000結構分析程式之分析結果比對，確認以SAP2000對完全張力體進行分析時，構件設定、預力施加、結構分析方式之正確性。
最後透過實際構築二分之一縮尺之壓桿交錯曲面系統，驗證本研究設計之可行性。實構過程根據不同材料接合需求、邊界支承條件限制，以現有五金材料配合可取得之實構基地，設計各構件細部並規劃組裝過程，最終完成薄膜式完全張力體之構築。

This study utilized bamboo in tensegric membrane structure to construct a space that can be used as architecture. Being widely distributed in Taiwan, bamboo is an environmentally-friendly material with high availability due to its fast growing and low energy consumption. On this account, bamboo was used in this study as the building material for a lightweight structure proposal. Tensegrity is a relatively new kind of structural system, which contains only pure compression and tension members. The relatively small section it needs makes the system essentially lightweight.
Before the design, material tests were performed to verify the mechanical properties of the bamboo and the membrane. Then, the stretch and non-stretch fabric was used as the membrane to study the possible structural form and stability. Two major systems, twisted prism system (TPS) and curved surface system with staggered struts (CSS) were studied. In all proposals, polygon twisted prism (PTP) and parallely arrayed arch with staggered-strut system (PAAS) were further elaborated on form finding and prestress analysis. The analysis result of PTP was used to compare with the structural analysis result of SAP2000 in order to confirm the correctness of component setting, prestress applying, and the use of structural analytical approach when analyzing the tensegrity by adopting SAP2000.
Finally, a radiantly arrayed arch with staggered struts (RAAS) was practically constructed in a large scale (1:2) model to verify the feasibility of the design. The details of the practical construction were designed in consideration of available hardware, the restrictions of boundaries, and the site condition. The structure was constructed with manual labor and successfully stood on its own.
