Do flexible PV support structures have resonant frequencies?
Modal analysis reveals that the flexible PV support structures do not experience resonant frequencies that could amplify oscillations. The analysis also provides insights into the mode shapes of these structures. An analysis of the wind-induced vibration responses of the flexible PV support structures was conducted.
Does wind load affect a flexible PV support structure?
Wind Vibration Response of Flexible PV Mounting Structures To investigate the impact of fluctuating wind loads on the flexible PV support structure, the previously obtained wind load time histories were applied to a flexible PV support structure with a span of 30 m and a prestress of 50 kN.
How safe are flexible PV brackets under extreme operating conditions?
Safety Analysis under Extreme Operating Conditions For flexible PV brackets, the allowable deflection value adopted in current engineering practice is 1/100 of the span length . To ensure the safety of PV modules under extreme static conditions, a detailed analysis of a series of extreme scenarios will be conducted.
Which wind-vibration coefficient should be used for flexible PV support structures?
Considering the safety of flexible PV support structures, it is reasonable to use the displacement wind-vibration coefficient rather than the load wind-vibration coefficient. For the flexible PV arrays with wind-resistant cables discussed in this study, a recommended range for the wind-vibration coefficient is 1.5 to 2.52.
