MECHANICAL PROPETIES AND EXPERIMENTAL STUDY
In order to study the mechanica properties of the fixed photovoltaic bracket and its failure under wind load, the full-scale photovoltaic bracket specimen was designed and the destructive test
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.
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.
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.
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.
