构造大跨度空间结构是现代建筑空间结构的发展方向。从古至今人类不断创造空间跨度的新记录，目前，人类已经建造了一批大跨度空间结构，这些结构的跨度在人类建筑史上达到了空前的水平。然而探索新的结构形式、构造更大跨度的空间结构一直是人类追求的目标。弦辐结构正是在这一背景下，为建造超大跨度的空间结构而提出的一种新型的结构形式。本文提出弦辐结构的基本概念、着重描述了弦辐结构的空间构形并对其结构特点作了进一步研究和分析。
The construction of large-span spatial structures is the development direction of modern architectural spatial structures. Since ancient times, mankind has continuously created new records of spatial span. At present, mankind has built a large number of large-span spatial structures. The span of these structures has reached an unprecedented level in the history of human architecture. However, exploring the new structural forms and constructing a more spanned spatial structure has always been the goal pursued by mankind. Chord and spoke structure is a new type of structure proposed in this context for the construction of super-span spatial structure. This paper proposes the basic concepts of chord and spoke structure, focuses on the spatial configuration of the chord and spoke structure, and further studies and analyzes its structural characteristics.
