In the photovoltaic (PV) solar power plant projects, PV solar panel (SP) support structure is one of the main elements and limited numerical studies exist on PVSP ground mounting steel frames to be a research gap that has not be addressed adequately in the literature.
Based on a typical photovoltaic support failure case, this study involved detailed research on the design load and joint connection measures of photovoltaic supports. First, the general design software SAP2000 (V22.0.0) was utilized to compare the loads in photovoltaic support structure design among Chinese, American, and European codes.
Based on design information and on-site observations, the loads acting on photovoltaic supports primarily include the weight of the photovoltaic panels, the wind load, the snow load, and the construction load. Additionally, the Chinese code NB/T 10115-2018 mandates the consideration of the longitudinal wind load on photovoltaic supports.
The support configuration at both ends is one of the key factors affecting the load-bearing capacity of photovoltaic support structures. A brace that is too weak can exacerbate the deformation of the structure, leading to greater damage. It is necessary to avoid out-of-plane deformation by optimizing the joint connection at the end of the brace.
