Instability mechanism and failure criteria of large-span flexible PV support arrays under severe wind
SOLAR ENERGY(2023)
摘要
•The wind pressures distribution characteristics of large-span flexible PV support array surface were analyzed.•The wind-induced instability processes of the large-span flexible PV support array are effectively simulated.•The instability mechanism of the large-span flexible PV support array is revealed.•The dual failure criteria based on structural deformation and energy increment are proposed.
