“杂交”结构体系的应用和发展
|
摘要
“杂交”结构体系是一种将不同形式的基本结构经优化组合而成的新型结构体系。本文介绍了该结构体系的组成方式，指出拉索是一个比较活跃的单元体，它具有与各类刚性、柔性结构进行广泛组合的可能性，由此可以构成斜拉结构、预应力结构等一系列具有特色的“杂交”体系。文中还结合现有的一些“杂交”结构工程实例进行了论述和分析。
This paper present a new type of structural system-hybrid structural system which is an optimum combination of sereval basic structures. It is more ecnomical and reasonable than the original structure. This paper also discusses the combination form of the hybrid structure, and points out that the cable is an active element house of its possibility to combine with almost all kinds of rigid and flexible structures. With this cable, a series of hybrid structures such as cable-stayed structures and prestressed structures are therefore obtainable. Furthermore, the hybrid structure provided in this paper is discussed and analyzed in conjunction with sereval hybrid structures existing in present engineering practice.
