Starting from funicular models, chain models and hanging membranes, the role of 3D physical models in optimized shape research is the basis of form-finding strategies. Advances in structural optimized shape design derive from the wide spread of special digital form-finding tools. The goal of this paper is to test and evaluate interdisciplinary approaches based on computational tools useful in the form finding of efficient structural systems. This work is aimed at designing an inverse hanging shape subdivided into polygonal voussoirs (Voronoi patterns) by relaxing a planar discrete and elastic system, loaded at each point and anchored along its boundary. The workflow involves shaping, discretization (from pre-shaped paneling to digital stereotomy) and structural analysis carried out using two modeling approaches, finite element and rigid block modeling, using an in-house software tool, LiABlock_3D (MATLAB®), to check the stress state and to evaluate the equilibrium stability of the final shell.

使用 Voronoi 模式查找数字表格

从索道模型、链模型和悬挂膜开始,3D 物理模型在优化形状研究中的作用是找形策略的基础。结构优化形状设计的进步源于特殊数字找形工具的广泛传播。本文的目标是测试和评估基于计算工具的跨学科方法,可用于有效结构系统的形式查找。这项工作旨在通过放松平面离散和弹性系统,在每个点加载并沿其边界锚定,设计一个反向悬挂形状,细分为多边形 voussoirs(Voronoi 模式)。工作流程涉及使用两种建模方法进行的成型、离散化(从预成型镶板到数字立体切割)和结构分析,® ),检查应力状态并评估最终壳的平衡稳定性。
