ABSTRACT

This paper introduces a bioinspired structure design method in the conceptual stage and takes the human femur section as an example, to extract the structural principle from the natural form, and summarizes as the morphological operation rules. The morphological manipulation rules provide a geometric feedback-based design process of both the building structural performance and its space with the manipulation rule of Graphic static. While extracting building structural principle, the layout optimization method is applied to obtain the force flow inside the nature biological form boundary under a certain load, and the force flow is presented with strut and tie model, summarizing the structural characteristic of human femur. The combinatorial and transformation methods of graphic statics are employed in the morphological operation stage to transform the form diagram while maintaining equilibrium, which facilitates designers to explore the structural form from both performance and space perspectives. Finally, the design process of a stadium inspired by the human femur is taken as an example to demonstrate how the introduced workflow can be used in the conceptual design stage and optimization of buildings.

摘要

本文介绍了概念阶段的仿生结构设计方法，并以人体股骨截面为例，从自然形态中提取结构原理，总结为形态学操作规则。形态操纵规则利用图形静态操纵规则提供了基于几何反馈的建筑结构性能及其空间设计过程。在提取建筑结构原理的同时，应用布局优化方法获得一定荷载作用下自然生物形态边界内的力流，并将力流用strut and tie模型呈现，总结了人体股骨的结构特征。在形态运算阶段采用图形静力学的组合和变换方法，在保持平衡的同时变换形式图，便于设计师从性能和空间两个角度探索结构形式。最后，以受人类股骨为灵感的体育场设计过程为例，展示了引入的工作流程如何用于概念设计阶段和建筑物的优化。
