[0002] Steel structures have the characteristics of high strength, light weight, strong deformability, good toughness, and high reliability. The application of steel structures in construction projects can effectively improve the performance of construction projects and save construction project costs. Therefore, with the rapid development of the construction industry, the use of steel structures has gradually become more extensive, especially in large-span structural systems.

[0003] However, although steel structure projects are more suitable for large-span systems due to their light weight, when designing steel structures, the safety and stability of large-span steel structures are often taken into consideration. Steel structure systems often contain grid or truss structural units. These structural units are often large in size and do not have the conditions for assembly on site. Therefore, they are transported to the site for installation after being manufactured by the manufacturer. However, during transportation, due to the large size of the structural units, scratches, deformation of components or other reasons may occur, resulting in untimely transportation. Such phenomena are detrimental to both the quality and safety of the structure itself and the progress of the project.
