为构造超大跨度空间结构而设想的一种新的结构形式——弦辐结构

NEW STRUCTURAL FORM USED TO ACHIEVE SUPER LARGE SPAN SPACE—? HORD SPOKE STRUCTURE

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。

Abstract The search for a means to achieve super large span space is one of the orientations of modern architecture. Man has struggled to conquer “span” since the beinning. Now many structural systems were developed to meet the increasing demands for large unobstructed areas. Those achievements are unprecedented. However, finding new structural form and creating larger span space has been important objective of human beings in future. For this reason, a new type of space structure——chord spoke structure that used to achieve super large span was presented. In thie paper, the basic concept of chord spoke structure was described and some valuable results of primary study were carried out.
