What is a large-span flexible PV support structure?

Proposed equivalent static wind loads of large-span flexible PV support structure. Flexible photovoltaic (PV) support structure offers benefits such as low construction costs, large span length, high clearance, and high adaptability to complex terrains.

What is the shielding effect of a flexible PV support structure?

While in the middle span, as α increases 10° to 20° and then to 30°, the shielding effect increases from 13.9 % to 59.8 % and then to 89.1 %. For aeroelastic model tests, it can be observed that the flexible PV support structure is prone to large vibrations under cross winds.

Why is flexible PV support structure prone to vibration under wind excitations?

However, due to the large flexibility and small damping of the cable system, the flexible PV support structure is prone to large vibration under wind excitations , , . The wind load of flexible PV support structure is the most important controlling factor of structural safety, and the primary factor in the design process.

Do flexible PV support cables reduce vibration?

Liu et al. , designed a 33 m-span flexible PV support aeroelastic model and conducted wind tunnel tests to verify the effectiveness of three types of stabilizing cables in reducing vibrations in the support structure.

What is the mean vertical displacement of a flexible PV support structure?

The mean vertical displacement Zv of the flexible PV support structure at α = 10°, with wind direction angles β = 0° and β = 180°, along with varying wind speeds, are shown in Fig. 20, Fig. 21. The mean vertical displacement of both the side and mid spans increases with increasing wind speed.

Why do PV modules have wind-resistant anchor cables?

Due to the wind-resistant anchor cables, which are anchored to the foundation and set in both the windward and leeward zones, the vibration of the PV modules and load-bearing cables under wind suction is suppressed.
