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.
