Given the sensitivity of flexible PV support structures to wind loads and their pronounced wind-induced vibration responses in large-span settings, the development of effective vibration control measures is of
Aeroelastic model wind tunnel tests The wind-induced vibration response of flexible PV support structure under different cases was studied by using aeroelastic model for wind tunnel test, including different tilt angles of PV modules, different initial force of cables, and different wind speeds.
Discussion The wind load is a vital load affecting PV supports, and the harm caused by wind-induced vibration due to wind loads is enormous. Aiming at the wind-induced vibration of flexible PV supports, a PV building integration technology [86, 87] was proposed to reduce the harm caused by wind vibration.
For aeroelastic model tests, it can be observed that the flexible PV support structure is prone to large vibrations under cross winds. The mean vertical displacement of the flexible PV support structure increases with the wind speed and tilt angle of the PV modules.
Furthermore, little attentions were paid on the critical wind velocity of the flexible PV modules support structures. In this study, wind-induced response and critical wind velocity of a 33-m-span flexible PV support structure was experimentally studied by using a non-contact video displacement measuring system.
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.
However, because the cable-supported PV modules also possess high flexibility and low damping, they are prone to large vibrations under wind excitation. In the present study, a series of wind tunnel tests were conducted to simulate the wind-induced vibration (WIV) of a type of cable-supported PV modules.
