Description

Technical Field

[0001] The present invention relates to the technical fields of wind-induced vibration control of building structures and solar energy utilization, and particularly relates to a spoiler device and a spoiler system that can be installed on building structures such as bridges, high-rise buildings, or stadiums, which can not only suppress wind-induced vibration of the structure but also collect solar energy.

Background Art

[0002] In the field of construction engineering, many large building structures face the problem of wind-induced vibration. For example, long-span bridge structures have large flexibility and low damping, are highly sensitive to wind, and are prone to wind-induced vibration. Among them, vortex-induced vibration can occur at relatively low wind speeds, affecting driving safety and the fatigue life of the structure; high-rise buildings will sway under strong wind action, affecting the comfort of internal personnel and the safety of the building; large-space buildings such as stadiums have low structural stiffness and natural vibration frequencies close to the wind-induced vortex shedding frequencies, which are prone to vortex-induced resonance. The three-dimensional unsteady wind pressure distribution formed by the curved surface morphology is prone to induce aeroelastic instability (flutter / galloping), increasing the risk of structural damage. Certain measures need to be taken to control or weaken the wind-induced vibration of the above structures.

[0003] Currently, there are many drawbacks in the control measures for wind-induced vibration of building structures. For example, the tuned mass damper (TMD) used on bridges is costly and can only suppress vibrations of specific orders; some aerodynamic measures adopted in buildings, such as installing grilles, etc., although they can control multi-order vibrations, have problems of large volume and large mass, which will increase the static load and cost of the building structure, and the difficulty of maintenance and replacement is also relatively large. While traditional spoilers have the advantages of small volume, low cost, and easy installation and maintenance, they are only used for wind-induced vibration control and have a relatively single function.

Summary of the Invention

[0007] As a further improvement of an embodiment of the present invention, the solar flow suppressor is connected to the building structure through a connecting component.
