摘要
本文所讨论的索杆张力结构是由索和杆为基本构成单元、通过预应力提供体系刚度的一类空间结构体系.由于其结构构成和受力机理与常规结构有较大的区别,如何正确系统地认识和理解该类结构是目前科研和设计人员面临的重要问题.本文从结构形态的角度,系统地阐述了索杆张力结构设计的主要阶段以及各阶段需要解决的主要形态问题.同时进一步讨论各类形态问题的一般性分析方法和研究思路.
The Cable-Strut Tensile Structure (CSTS) discussed in this paper is a class of structures which is mainly composed of cables and struts and must be prestressed to provide the structural stiffness. Because the structural conformation and mechanical principle are different from those of traditional structures, how to built up a correct and systematic comprehendsion on the CSTS is a common problem to researchers and engineers. The purpose of this paper is to present an overall expatiation on CSTS in the aspect of structural form. Also, the analysis methods and research directions to solve this problem are discussed in this paper.
