In addition to the permanent load and variable load, the design of the outdoor giant Ferris wheel should also consider the impact of special loads such as earthquakes and temperature on the overall structure when necessary.
The main loads experienced by the Ferris wheel during normal operation include permanent load, live load, cable pretension, icing load, wind load, seismic load and so on. In the design of the Ferris wheel, these loads are mostly calculated and analyzed. As the height of world's outdoor giant Ferris wheel structure is constantly being refreshed, higher requirements are put forward for the design of the Ferris wheel structure. Structural strength, rigidity, stability and reliability are important factors that must be considered in the design of the Ferris wheel.
Outdoor giant Ferris wheels are generally used at -10℃ to 40℃. In cold winters, there is often accumulated snow at this temperature. In the case of accumulated snow, the Ferris wheel is required to stop running, and it can continue to run after the snow is cleared. In fact, due to the high cost of operators to purchase Ferris wheels, the basic purchase prices of most of the famous Ferris wheels that exist now are very high, so operators need to make the Ferris wheel run as much as possible without affecting the structure and safety.
The phenomenon of thermal expansion and contraction caused by temperature changes is a basic property that exists in most natural objects. A large number of studies on the temperature effect theory of giant Ferris wheel structures or components show that the temperature effect on large steel structures cannot be ignored. Although temperature has little effect on general steel structure buildings, it has a greater impact on super large steel structure buildings. It is necessary to calculate the temperature stress and the deformation caused by the temperature in the design. Therefore, for the giant Ferris wheel structure, the influence of the temperature effect must be considered. At present, many large-span structural designs have studied the temperature effect in detail.
