In the manufacturing and installation process of the outdoor giant Ferris wheel structure, there are inevitably errors or initial defects. For example, the rim may be bent or twisted; the bracket column will bend and the pipe wall will be deformed locally during welding; the support column foundation will settle unevenly; the braking force of the drive system does not match the design value, etc.
The force performance of the Ferris wheel structure is affected by the initial defects. But for different defects, the sensitivity is different, too. That is, it is more sensitive to certain types of defects, but not sensitive to other types of defects.
In order to ensure the safety of the giant Ferris wheel in use, people must consider the main defects that affect the force performance of the Ferris wheel structure in the design, and it is necessary to accurately calculate the impact of sensitive defects on its force performance and bearing capacity.
In the actual construction, the sensitivity of the Ferris wheel structure with various geometric defects must be analyzed through authentic engineering examples, and the defects which can more affect the Ferris wheel structure can be found, which can provide a reference for the design. In this way, it is convenient to particularly control the relatively more sensitive defects in the actual project, appropriately reduce the control requirements for insensitive defects and improve the economic performance of the Ferris wheel structure.
