摘　　要：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 structures, tree structures have been more and more widely used because of clear load transfer, reasonable bearing and beautiful appearance. This paper clears up the definition that tree structures are a kind of structure with certain supporting function, which are designed on the basis of researching the shape and stress characteristics of trees in nature. The composition and the coding of tree structures are specified. Combined with engineering projects, seven different classification methods of tree structures are brought out according to type of upper structure, joint force, combination with other structures, stiffness of upper structure, series and space of tree structures. On the basis of explaining the benefits of tree structures, the application of tree structures in stuttgart Airport, Rice Cube and a toll station of Mohe airport highway is analyzed, which can provide some references for the analysis and design of tree structures.
