Mosaic Sampling: Generative Scheme for Spatial Structures Design

Because of their construction efficiency, regular tessellations are standardly applied in the design of discrete spatial structures. However, digital fabrication enables the application of intricate patterns that may be structurally even more rational, such as patterns based on isostatic (principal stress) lines or the application of patterns inspired by nature. This study explores the potential use of ornamental patterns in the design of spatial structures’ mesh geometry. A generative design tactic based on structural form-finding is suggested, wherein structural mesh geometry is created using mosaic samples. While computational form-finding is typically used in spatial structures design, the suggested design tactic is unique because it uses the sampling concept to define a generative system. In this context, sampling is an act of taking a fragment, or a sample, of one design and its implementation in different design solutions. Specifically, a series of mosaic designs were used to derive initial mesh geometry applied to the form-finding of spatial structures. Since form-finding directly links configuration with force in a closed loop, structurally rational designs are produced from the initial mesh patterns derived from mosaics. The effectiveness of the suggested approach was tested through design explorations. Further, the approach may also be extended to other patterns that are not conventionally used in the design of spatial structures.
