Abstract: In view of the design concept of the large space general assembly experiment center, the structural scheme selection of the airship hanger structure was discussed. The mechanical characteristics of inclined 3-D steel truss, single-layer reticulated shell and double-layer reticulated shell which composed of the inclined plane truss arch were compared. The results show that the effect of the last method is better, and the construction scheme will be introduced. On the other hand, the airship gate styles from the past experience were also summed up. As a consequence, the cylindrical surface rotate gate was put forward creatively, and the design concept of the system of hanging hoisting machine was determined as well. In the end, the design concept of double-layer reticulated shell composed of the inclined plane truss arch was evaluated. In summaries, the key points were presented. The primary analysis results were also drawn.

Keywords: large space; hangar gate; structural scheme selection
