超越尺度:大跨壳体建筑的微结构仿生设计研究

Beyond Scales: Micro-Structural Biomimetic Design of Shell Structure in Long-Span Architecture

壳体结构在自由曲面与网格布置方面的研究与设计相对成熟,却与新时期下大跨建筑工程向性能化、可持续、交叉创新发展等需求存在鸿沟。针对这一矛盾问题,提出大跨壳体建筑的微结构仿生设计新思路,首先是从复杂性科学与数字化技术两个维度对大跨壳体形态系统进行解读和层级化重构;进而尝试在微结构层级中引入仿生学,从涌现主体、生成逻辑、环境响应3个方面对微结构的仿生设计流程进行建构。最后提出未来壳体建筑发展途径,试图实现微观与宏观的融合和超越。

The research and design of shell structure is relatively mature in free-form surface and grid layout, but there is a gap with the performance-oriented, sustainable, and cross-innovative development of long-span architectures in the new era. In response to this contradiction, this paper explores new ideas of micro-structure bionic design of long-span shell architecture.Firstly, it interprets and hierarchically reconstructs the longspan shell form system from two dimensions of complexity science and digital technology. Then, it introduces bionics into the hierarchy of microstructures, and constructs the bionic design process of microstructures in three regards: emergence of the subject, generative logic and environmental response.Finally, the paper advocates for the future development approach of shell architectures and makes an attempt on the integration and transcendence of micro and macro..
