摘　　要：在回顾弦支穹顶结构产生、发展及应用的基础上,结合弦支穹顶结构的特点,对该新型结构体系的概念进行延伸和拓展。以此为依据,对弦支穹顶结构体系的分类方法进行研究,提出按照上部刚性层结构和下部张拉索杆体系的组成特点进行总体分类的方法,根据该方法对弦支穹顶进行较系统的分类,既总结了目前已有的结构类型,也构建了部分新的结构形式。通过分类研究,不仅对该新型结构体系的选型、设计和施工等方面提供有益的参考,还将启发人们不断思考,创造出更多的结构新体系或新形式。Through reviewing the foundation, development and application of suspendome structures, the concept of such structural system is extended in combination with its characteristics. The classification method for suspendome structures is studied on the basis of the conceptual extension. A new method for generally classifying the structural system is presented according to the composition characteristics of the upper rigid layer structure and the lower cable-strut system. Systematic classification is carried out afterwards, in accordance with this method, in order to help both the generalization of previous structural types and the establishment of new structural forms. The study on classification issues should be beneficial to form-selection, design and construction of such structural system.
