Changes in the node stiffness of container houses have a greater impact on the stress and deformation of the layout, especially the components adjacent to the nodes, because the connection nodes between the roof trusses and columns, the connection nodes between floor beams and columns, and column foot nodes are the primary nodes that bear stress on the layout. The overall stress performance of the container house was analyzed by changing the stiffness of these nodes. The result of the analysis is that compared with the completely rigid connection and the ideal handover situation, the stress distribution of structural components during semi-rigid connection is more even, and the stress on the steel structure components is more Reasonable.

It is recommended that the main node connection methods of color steel plate containers are: the connection nodes between roof trusses and columns are close to hinged connections, the connection nodes between floor beams and columns are close to rigid connections, and the stiffness of column foot nodes is close to rigid connections.
In the actual production, processing, transportation and demolition process of color steel plate container houses, they inevitably have various shortcomings. At the same time, the components are relatively slender and the cross-sectional size is relatively small, resulting in initial shortcomings compared with other structures. Speak loudly.
Floor beams and columns are the main stress-bearing components of the container structure. The parts where the maximum internal force and deformation of the structure occur are also the floor beams and columns.
Through the analysis of the initial defects of floor beams and columns, it is found that when floor beams fail, they will have a greater impact on the vertical displacement of the structure. When a column fails, the horizontal displacement of the structure will be greatly affected. When the floor beams and columns fail at the same time, the adverse impact on the structure will be greater.
