Architects have been following nature in their constructions for a long time. Observations of nature reveal that it has many highly developed structures that provide scientists and engineers with a lot of useful clues for creating more efficient structures and building forms. Therefore, revealing systematic thinking about natural species is a crucial requirement for today's buildings. A software analysis method was used to design four modules in the roof structure of the Iranian University of Science and Technology's exhibition. The roof structure is based on the Voronax structure, which is a relaxed form of Voronoi, which is seen in the structures of many natural creatures. They were analyzed in terms of optimization and structural simulation using Grasshopper plugins and tools by taking into account Von Mises stress in the structural design. The results indicated that by increasing the density of Voronax cells in the areas with high Von Mises stress concentration, a more efficient structure could be achieved in terms of load-bearing and designing predefined free-form roof structures. By analyzing predefined roof structures in an optimum way, the study took a step toward optimizing these kinds of structures.

四个设计屋顶模块的结构优化:受 Voronax 网格壳结构的启发

长期以来,建筑师一直在他们的建筑中遵循自然。对大自然的观察表明,它有许多高度发达的结构,为科学家和工程师创造更有效的结构和建筑形式提供了许多有用的线索。因此,揭示对自然物种的系统思考是当今建筑的关键要求。伊朗科技大学展览馆屋顶结构采用软件分析方法设计了四个模块。屋顶结构基于 Voronax 结构,这是 Voronoi 的松弛形式,在许多自然生物的结构中都可以看到。通过考虑结构设计中的 Von Mises 应力,使用 Grasshopper 插件和工具在优化和结构模拟方面对它们进行了分析。结果表明,通过增加 Von Mises 应力集中区域的 Voronax 单元密度,可以在承重和设计预定义的自由形式屋顶结构方面实现更有效的结构。通过以最佳方式分析预定义的屋顶结构,该研究朝着优化此类结构迈出了一步。
