弦支网架结构体系概念及特性研究

网架结构是较为常见的一种空间结构形式。在传统的预应力网架结构的基础上,引入张拉整体思想,形成建筑效果美观的弦支网架结构。按照网架结构的常用类别定义,给出弦支网架结构的分类形式。对比研究网架结构和弦支网架结构自身的基本特性,提出弦支抽空型网架结构的概念,并对其进行静动力性能分析。结合工程实例,介绍弦支抽空型网架结构的特点和应用情况。

RESEARCH ON THE CHARACTERISTICS AND CONCEPT OF THE CABLE SUPPORTED SPACE TRUSS STRUCTURE

Space truss structure is widely applied in practical engineering as a space structure.Based on traditional pre-stressing space truss structure,the concept of tensegrity system is introduced into space truss structure to form a cable supported space truss structure is formed and its architectural effect is superior.Classification form of the cable supported space truss structure is given.It is comparatively studied the characteristics of the cable supported space truss structure and the space truss string structure,the concept of the evacuation cable supported space truss structure is proposed.The static and dynamic behavior of the evacuation cable supported space truss structure is researched.At last,characteristics and application of the cable supported evacuation space truss structure are introduced.
