[Abstract]:Vertical assembly test plant is one of the most important industrial buildings in the technical area of space launch site. It is the key facility to realize vertical assembly, vertical test and vertical transportation of "three vertical modes" in space launch site. The steel structure is mostly used in the vertical assembly test building of the spaceflight launch site at home and abroad, and the concrete structure is used partly. There is no vertical assembly test building with steel-concrete composite structure. This paper takes the new space launch site vertical assembly test building as the engineering background. On the basis of summing up the structural forms and characteristics of the vertical assembly test building at home and abroad, the structural system of the steel concrete composite structure vertical assembly test building is studied systematically. The concrete is compared and analyzed in this paper. Structure. The advantages and disadvantages and engineering cost of steel structure, steel-concrete composite structure and three forms of vertical assembly test workshop. According to the characteristics of the hall roof of the vertical assembly test workshop, the reinforced concrete box beam roof and steel truss roof are selected. Three types of single-story hinged steel roof structure were selected and compared to study their influence on the main structure and their advantages and disadvantages. Through the analysis of the characteristics and requirements of the moving lifting platform and vertical transfer gate of the core components of the vertical assembly test plant. The special research is carried out on the fixed platform supporting the movable lifting platform and the door frame connected to the vertical transfer gate. The fixed platform scheme of cantilever truss and the structural scheme of "convex" integral steel truss gate door frame are determined. In addition, SATWEN PMSAP is applied in this paper. The structural design software, such as ETABS, is used to calculate and analyze the stress situation of the steel concrete composite structure vertical assembly test building under various working conditions, and the calculation results of several kinds of software are compared. In order to verify the accuracy of the calculation results, considering that the project is located in the strong typhoon landing area along the coast of China, in order to ensure the safety of the structure against wind. The wind resistance of the vertical assembly test building is also studied by wind tunnel test. The wind pressure distribution of the vertical assembly test building under the condition of door closure and open is given. The experimental data and guidance are provided for the wind-resistant design of the structure and components of the powerhouse. The structural design results of the steel-concrete composite structure vertical assembly test powerhouse show that:. Steel-concrete composite structure vertical assembly test building as a new type of space launch site vertical assembly test building. It has the advantages of safety and reliability, advanced technology, reasonable economy and so on. It can be popularized and applied in the future space launch site vertical assembly test building and similar building. The structural Design Research of Steel-Concrete Composite structure Vertical Assembly Test Factory is for the Space launch site Vertical Assembly Test Plant. The supplement of the housing structure system. Some methods and suggestions obtained from the study can provide a reference for the structural design of the space launch site vertical assembly test building in the future, and have important social and military benefits.
