张力结构节点设计评述

Introduction to Node Design for Tensile Structures

张力结构是空间结构体系中靠预应力提供刚度的一类特殊结构 ,由于利用了材料的强度而提高了结构的刚度 ,所以 ,节点设计是张力结构设计以及分析中的重要方面。本文从节点的概念设计、刚度设计、强度设计、极限承载力分析以及制作安装等角度综合考虑 ,分类讨论了张力结构的节点设计问题。

Tensile structure is a pecial kind of space structure system whose node design is very important not only to the structural analysis, but also to the system construction. In this paper considering the concept design, stiffness design, strength design, analysis for ultimate carrying capacity and construction design, etc., the authors present the design and analysis methods for node design, and present some useful node type of tensile structures. By using 3D modelling software some node models are presented in this paper.
