The cable-strut tensile structure system is the floorboard of tensile structure, cable dome structure, spatial cable-joist structure, and some other prestress balance structures made up of tensile cables and press struts. Such system composed of continuous tensile cable and disconnected press struts has extremely high structural efficiency, represents its advantage that the anciently spatial structures didn't have. More and more people have been attracted by its ingenious design, excellent performance, and economic cost. The application of cable dome structure and cable-joist structure in project ulterior explain the powerful libido of the cable-strut tensile system. But up until now, there is no application of the actual project in the hinterland of our country in such new structure, the cognition of the cable-strut tensile structure system is not comprehensive, and the study work in this aspect was still been constantly progressing.At present both our country and abroad countries'research of cable-strut tensile structure mostly concentrate on geometry topology, prestress equilibrate state analysis, geometrical stability determinant, load state analysis, construction process track, text study, and so on. The study of cable dome which is the magnum opus of cable-strut tensile structure is mostly focus on geometry characteristic and stability, autonomous inner force mode and prestress distribution optimization analysis, the study on the problem of prestress loss ,nonlinear finite element basic theory analysis, construction simulation analysis, static and dynamic characteristic model experimentation and some other aspect. Its study method has already switched from rationalism to theory service the fact; solve actual project problems, from static domain to dynamic domain. But the theory is not uniform and complete as a whole.In this text the research actuality in and out of the country, project application circs, and the problem which need to solve of cable-strut tensile structure were summarized after reading plentiful domestic and overseas reference literature, stress introduced cable dome which is the magnum opus of cable-strut tensile structure. Discussed the characteristics and merits of cable dome, thereby complete the conceptual research of cable-strut tensile system and cable dome structure, and based on the work of former pursuer, the main study direction and technique course were put forward.The foundation and resolution of nonlinear finite element equation of cable dome structure were farther explained, static performance of cable dome was analyzed according to finite element analysis software -ANSYS, the components internal force and displacement...
