Abstract

This paper presents a form-finding approach for Injection 3D Concrete Printing (I3DCP) using Vector-based Graphic Statics (VGS). This approach adopts a top-down strategy, initiating a preliminary global design in the form of a space truss and integrating structural and fabrication constraints specific to I3DCP. A form-dependent self-weight load is applied throughout the form-finding process until the structure achieves static equilibrium. As the current I3DCP setup is mounted on a robotic arm with a stationary base, the feasibility of the designed structure for I3DCP is assessed, ensuring compatibility with the robotic arm’s workspace. Structures exceeding the workspace boundaries are segmented and individually optimised, subject to topological and geometrical constraints. The optimised segments are then merged into a single assembly to complete the process. This approach is demonstrated through the design and construction of a 3-metre-span pedestrian bridge. This prototype is 3D scanned and then analysed via the finite element method to evaluate its mechanical performance.

基于矢量图形静力学的喷射三维混凝土打印空间桁架约束寻形

本文提出了一种基于矢量图形静力学（VGS）的注入式3D混凝土打印（I3DCP）的寻形方法。这种方法采用自上而下的策略，以空间桁架的形式启动初步的整体设计，并整合I3DCP特定的结构和制造约束。在整个找形过程中施加与形式相关的自重载荷，直到结构达到静力平衡。由于目前的I3DCP安装在固定基座的机械臂上，因此评估了设计的I3DCP结构的可行性，确保了与机械臂工作空间的兼容性。超出工作空间边界的结构被分割和单独优化，受拓扑和几何约束。然后将优化的部分合并到单个组装中以完成该过程。这种方法通过设计和建造一座3米跨度的人行天桥得到了证明。对该原型进行了三维扫描，然后通过有限元方法进行了分析，以评估其力学性能。
