[Abstract]:The ring cable-truss structure evolves according to the principle of wheel spokes. The structure system is light and beautiful and has obvious advantages in long span steel structure. This paper analyzes the structure and mechanical performance of the structure system, classifies it according to the architectural modeling and the force principle, and uses a variety of extension methods to mutate and expand the structure system to obtain a preliminary structural system library. In order to provide reference for engineering application. At the same time, the application status of ring cable-truss structure at home and abroad is summarized, and the characteristics of typical engineering case structure system are analyzed. The main application scope and classification of the structure system are obtained, and the self-balanced stress system of each kind of structural system is analyzed. The main points of the analysis of this kind of structure system are expounded. Through the analysis of shape finding, the selection and analysis of basic parameters, the construction tensioning and so on, the main points of analysis are discussed. The basic process, software application and analysis flow of ring cable truss structure engineering are given, and the feasibility of ring cable truss structure engineering application is illustrated.
