树状结构作为仿生结构的一种,以其力流明确、传力合理和外形美观的优势,逐渐得到越来越广泛的应用.本文明确了树状结构的定义:在研究自然界中树木的形态及受力特性的基础上,所设计的具备一定支承作用的结构;规定了树状结构的组成及编码;结合具体的工程实例,对树状结构按照承重类型不同、是否联合受力、造型不同、是否与其他结构组合、支承屋盖刚度不同、组成级数不同和组成空间不同共七种分类方式进行分类;在阐述树状结构优势的基础上,分析了斯图加特机场、天津米立方和黑龙江漠河机场公路收费站等实际工程,可为今后树状结构分析设计提供一定参考.
As a kind of biomimetic structure, tree-like structure is gaining more and more widespread use due to its advantages of clear force flow, reasonable force transmission and beautiful appearance.The paper defines the definition of tree structure: in studying the morphology of trees in nature And the stress characteristics of the structure designed to have a certain supporting role of the structure; provides for the composition and coding of the tree structure; combined with specific engineering examples of the tree structure in accordance with the different types of load, whether the joint force, different shapes , Whether it is classified according to the combination of other structures, different rigidity of supporting roof, different compositional stages and different compositional space; on the basis of expatiating on the advantages of tree structure, the author analyzes Stuttgart Airport, Tianjin Cube and Heilongjiang Mohe Airport toll booths and other practical projects, for the future analysis of tree structure design provide some reference.
