一、前言 圆形双层悬索是一种比较优良的屋盖结构形式。建筑工程部建筑科学研究院会作了一个直径15米的试验性建筑并作了模型试验。此后,北京、哈尔滨、沈阳等地都在大跨度建筑设计中采用。北京工人体育馆的建成,是我国在更大的跨度上采用圆形双层悬索结构的开端。 目前,设计圆形双层悬索结构采用的计算公式,多半是“大跨度悬挂式屋盖结构”一书中所发表的几篇文章。其中主要的是建筑工程部建筑科学研究院所写的“我国
I. INTRODUCTION The circular double-layer suspension cable is a relatively good roof structure. The Building and Construction Research Institute of the Ministry of Construction Engineering made a test structure with a diameter of 15 meters and conducted a model test. Since then, Beijing, Harbin, and Shenyang have been used in large-span architectural designs. The completion of the Beijing Workers Stadium is the beginning of the circular double-layer suspension structure adopted by China in a larger span. At present, most of the calculation formulas used for designing circular double-layer suspension structures are published in the book “Long-Span Hanging Roof Structures”. The main one is "China, written by the Institute of Building Science of the Ministry of Construction and Engineering.
