The reserves of traditional fossil energy are decreasing day by day, and the environmental pollution problem caused by consuming fossil energy is becoming more and more serious, and the harm caused by environmental pollution is becoming increasingly prominent. At the same time, about 2 billion people in the world still cannot obtain normal energy supply. Therefore, the research on renewable new energy is crucial for sustainable development. In the field of new energy, solar energy has become the focus of attention due to its unique advantages. The rich solar energy is inexhaustible and has extremely broad development prospects. At the same time, with the vigorous development of the photovoltaic industry, it is necessary to find more large-area light-receiving surfaces that can be provided with photovoltaic panels. Photovoltaic parking sheds have emerged as the times require, enabling large open-air parking lots for heavy trucks to enter the ranks of available resources in the photovoltaic industry. Photovoltaic carports have been gradually popularized. However, in the design of large-span photovoltaic carports, how to ensure the structural stability and the ability to resist natural disasters, while taking into account aesthetics and economy, is still an unsolved problem.
