碩士 === 國立成功大學 === 建築學系 === 104 === In this study, the corrugated board boxes were utilized as structural elements. When combined with vacuum pre-stressed system, they could construct spaces and to be the application to architecture. The boxes were made use of spacing components in which the NY/LLDPE membrane was taken advantage of enveloping component and forming an airtight space. The pre-stress caused by pressure difference of the system and the atmosphere could engage components, and reduce the amount of glue or bolts. The membrane could be the waterproof coating simultaneously. Moreover, the reversibility of vacuum system could reduce the cost of recycling corrugated boards and increase the proportion of recyclable boards. Above all, several types of small-scaled models were assembled as trials to combine the corrugated board boxes with vacuum pre-stressed system. The sliding joints or latches, which used as connectors of the boxes, were developed in this study to reduce the usage of tools. Grasshopper, an algorithmic modeling software, was then used to divide the curved surface and output the expansion plan of the boxes. Material and element tests were performed to determine the mechanical properties of corrugated boards and membrane which might decide the material direction applied to the model. MidasGen, a structural analysis software, was used to confirm that the compression stress could compensate for the tensile stress which caused by the bending moment and the analysis result from MiadasGen was utilized to adjust the final form of structure Finally, a full-scaled model of pointed arch was practically constructed. By adopting digital manufacturing, a faster process and a more precise model is achieved. The structure could be constructed only with manual labor and was placed in external environment to observe and record the performance which could be a reference to designers or planers.
