4.1. Model Establishment To further analyze the deformation of photovoltaic supports, a numerical simulation was conducted using the ABAQUS finite element analysis software, which allows for a more realistic consideration of the connection conditions of components.
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.
All components of the photovoltaic supports were modeled using eight-node linear hexahedral solid elements (C3D8R). The simulation included parameters where two or three bolts were installed at the purlin hangers to investigate the effects of different connection methods on joint deformation; a schematic diagram is shown in Figure 7.
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.
