Based on a photovoltaic bracket optimization project
a full-scale photovoltaic bracket structure is fabricated in order to study its bearing capacity under wind load. A static loading test
along with numerical simulations
is performed to evaluate the mechanical properties of the structure. Furthermore
the force response of the structure under negative wind pressure conditions is examined. The results indicate that the structural members remain within the material yield stress limits
and their deflections satisfy the code requirements. The finite element simulation closely matches the experimental results
validating the accuracy of the simulation method. In conclusion
the photovoltaic bracket structure exhibits adequate bearing capacity under 140% of the design load
with local instability of the steel beam identified as the primary mode of structural failure.
