6 FAQs about [The photovoltaic support construction spans too many servers]

Do large-span flexible PV supports fail at critical wind speeds?

Li and his team studied the instability mechanisms and failure criteria of large-span flexible PV supports, concluding that triangular and cross diagonal braces fail at critical wind speeds of 51 m/s and 46 m/s, respectively. 2. Materials and Methods 2.1. Flexible PV Mounting Structure Geometric Model

Do flexible PV support structures deflection more sensitive to fluctuating wind loads?

This suggests that the deflection of the flexible PV support structure is more sensitive to fluctuating wind loads compared to the axial force. 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.

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 a flexible PV support structure exhibit a consistent response trend?

However, for mid-span acceleration, the wind suction condition results in greater values than the wind-pressure condition. Overall, it can be concluded that the flexible PV support structure exhibits a consistent response trend under both wind-suction and wind-pressure conditions. Figure 10.

Is a flexible PV support structure subjected to wind suction?

Fig. 13, Fig. 14, Fig. 15 show the flexible PV support structure is subjected to wind suction (β = 180°), the curves for the mean wind pressure coefficient in the span of S1 and S2 when the tilt angle α is 10°, 20° and 30°, respectively.

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.
