The total cost of the project was approximately 303.3 USD, and it required the use of 54 pieces of plywood measuring 121cm*484cm. Additionally, the project aimed to test the plywood unit's limited span and maximum tenacity. The intention is to emphasize the lightweight nature of the unit. As a result, it is not only easy to repair and assemble but also portable. The system serves not only as an efficient construction method but also as a type of falsework system or a temporary pavilion. Based on the results of the process model, the final unit size is determined to be 7*120cm. Furthermore, the anchor points are separated into units for individual connections or grid connections to prevent excessive loads on a single joint. First, the system was tested at a 1/2 scale by constructing a tri-gridshell mock-up. The height of the system's support stand was adjusted to achieve flexible form variations. Additionally, the maximum load-bearing capacity of the system was tested to determine its tenacity. By utilizing "Grasshopper," the system can simulate various grid shell forms and analyze the structural behavior of different deformed configurations through small-scale models. While considering the system on a larger scale, we need to divide the single line into multiple units to accommodate the limitations of material size. Our goal is to achieve the largest span and highly contoured system using thin veneer. This approach allows for efficient construction. We first simulated a perfect curved line using a catenary and then conducted practical tests to assess the impact of material weight. We determined the optimal size by balancing human-scale considerations and material weight. Moreover, it is important to allocate space for displacement, as the grid will start to compress when it is squeezed. We have also designed a support stand that can be adjusted to different angles to accommodate various states of compression. #timbershell #grasshopper3d #kangaroo2 #timberarchitecture #timbergridshell #gridshell #parametricarchitecture #lightweightstructures #tku #淡江建築 ＃畢業設計 ＃數位製造 ＃參數化設計 ＃輕量化 ＃網殼系統
