Abstract

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 was carried out by means of static loading. Through simulation and mechanical analysis, the design suggestions for the fixed photovoltaic support are given. The experimental results indicate that under the uniform load the failure mode of PV support is overall instability due to the torsion deformation of the purlins, but the bearing capacity of the beam and column is basically enough. The simulation model of fixed photovoltaic bracket is established by ABAQUS, and the numerical simulation results are compared with the test results. Through parameter analysis, the force mechanism and improvement measures for the photovoltaic brackets are discussed.
