The ring-shaped cable trusses structure evolves from the wheel spoke principle. The structure is lightweight and beautiful, which has obvious advantages in long-span steel structures. Based on the analysis of architecture and force performance of the structural system, according to the principle of architectural modeling and force-bearing, a variety of means of continuation were adopted to carry out the variation and expansion of the structural system to obtain the preliminary structural system library for engineering Application for reference. At the same time, the current situation of the application of ring-shaped cable trusses at home and abroad is summarized, and the characteristics of the typical project case structure system are analyzed. The main application scope and classification of the structure are obtained, and the self-balance force system of each type of structure system is analyzed. The main points of this kind of structural system analysis are expounded. Based on the analysis of the form-finding analysis, the selection and analysis of basic parameters, the construction tension and other analysis points, the basic process of the application of the ring-shaped cable truss structure and the software application and analysis process are given Means to illustrate the feasibility of ring cable truss structure engineering application.
