悬索结构的形式和设计选型

本文在简述悬索结构构成和受力特点的基础上,根据索网曲面形式和结构特征,对悬索结构进行了分类,介绍了各种单(双)曲面单(双)层悬索结构、交叉索网、斜拉结构的组成特点和国内外工程应用状况。文章还对悬索结构设计选型的若干主要问题,如建筑平面形状、结构跨度、刚度与稳定性、边缘构件与支承结构、屋面材料与排水等进行了论述,并提供了一些可供设计参考的有效措施。

TYPES AND DESIGN OPTIONS OF SUSPENDED CABLE STRUCTURES

In this paper, on basis of concise illustration of structural forming and behavior features of suspended cable structure, the author gives a reasonable classification of such structure accorrding to their surface types and structural features of cable nets. The compositional features of various types of single-curvature surface and hyperboloid, single (double)-layer suspended cable structure, hyperbolic parabclidal cable nets and cable-stayed structure are discussed in detail. Their application in home and abroad was described. Besides, the paper made a comprehensive statement of such main problems in optional design, as plan configurations, span of structure, stiffness and stability, boundary members and supports, roof materials and drainage etc. Some measures as a reference to design were proposed.
