Abstract This article introduces a novel equilibrium-based form-finding approach for air-supported structures that relies on vector-based 3D graphic statics and the Combinatorial Equilibrium Modelling (CEM). The proposed approach is particularly suitable for the conceptual phase of the design process, as it allows generating a wide range of design options of discrete air-supported structures without membrane material in real-time while taking into account the overall mechanical behaviour and the architectural potentials of these structures. Benchmarking analysis is carried out using Finite Element Method (FEM) models without the membrane material to validate the feasibility of the discrete structures generated using the proposed form-finding approach. The comparison between the models created by means of the proposed approach and the FEM models shows general compatibility in terms of the geometry of the structures and distribution of the internal forces. Moreover, a complete design method for air-supported structures that combines the strengths of vector-based 3D graphic statics and CEM, for the conceptual phase, and FEM, for the advanced phase with models that include the membrane material, is discussed.

使用 3D 图形静力学进行空气支撑结构概念设计的找形方法

摘要 本文介绍了一种基于矢量的 3D 图形静力学和组合平衡建模 (CEM) 的空气支撑结构新的基于平衡的找形方法。所提出的方法特别适用于设计过程的概念阶段,因为它允许在没有膜材料的情况下实时生成离散空气支撑结构的广泛设计选项,同时考虑到整体力学行为和建筑潜力这些结构中。基准分析是使用有限元方法 (FEM) 模型进行的,没有膜材料,以验证使用建议的找形方法生成的离散结构的可行性。通过所提出的方法创建的模型与 FEM 模型之间的比较显示了结构几何形状和内力分布方面的普遍兼容性。此外,还讨论了一种完整的空气支撑结构设计方法,该方法结合了基于矢量的 3D 图形静力学和 CEM(概念阶段)和 FEM(包含膜材料的模型的高级阶段)的优势。
