To establish standard system of fabricated container structure and obtain its mechanical characteristics, static mechanical analysis and seismic analysis were made on six sets of structures according to existing codes based on a typical plan of container building. The influence on structural performance by adding beams and columns or tension cables was also studied. The results indicate that: container building system is sensitive to wind load, which controls the section of members and seismic action is not a dominant factor; the effort to enhance lateral stiffness of container building by adding local columns and beams is not useful, while adding lateral tension rod can strengthen the structural lateral stiffness effectively. Finally, a connected joint used in container building was analyzed by multi-scale analysis. The results indicate that this joint can work well under every working condition and provide a technical reference of joint selection in similar container buildings.
