This article is based on an photovoltaic power plant project located in a high altitude area

and studies the structural damage that occurs during the operation of the flat single axis tracking bracket of the project.The relevant structural design parameter values are analyzed

and the influence of altitude on wind load values is considered.The basic wind pressure is corrected.The flat single axis tracking bracket structure is rechecked and verified using numerical analysis methods.The analysis results show that

according to the original design parameters

the structure was rechecked and calculated.The cross-sectional design strength and stable stress ratio of the main beam were insufficient

and the partial deflection of the components exceeded the allowable value;If the design wind speed takes into account the air density and mountain terrain coefficient correction

the bearing capacity and deformation of structural components such as steel pillars

main beams

and purlins do not meet the requirements.Finally

based on the numerical analysis calculation results

regional treatment measures are taken.
