Abstract
The present invention relates to a damage-free engagement device for wind-resistance of base-isolated structures. It includes a rubber seismic isolation support, upper and lower connecting plates, and a wind-resistance stiffness adjuster. The adjuster comprises a horizontal sliding bearing plate, a vertical guide groove, and components within the guide groove. These components include a bird beak plate, a disc spring group, and a stiffness adjustment bolt. The bird beak plate slides along the guide groove and engages with the sliding bearing plate. The invention improves horizontal stiffness while maintaining seismic isolation. It achieves a “wind lock-seismic unlock-wind lock” mechanism without component replacement, reducing maintenance costs.
