摘要：
The present invention discloses a stiffness control mechanism of a variable stiffness earthquake-isolation layer adapted to structural earthquake isolation and wind resistance, which comprises an upper flange plate connected to an upper structure, a lower flange plate connected to a base structure at the bottom, a pin key provided between hollow portions of the upper and lower flange plates, with the pin key movable up and down between the hollow portions of the upper and lower flange plates and the height of the pin key greater than the distance between the upper and lower flange plates, and a control means for fixing the pin key or controlling the pin key to move downward. The stiffness control mechanism of the earthquake-isolation layer of the present invention can automatically change stiffness of the earthquake-isolation layer, both effectively wind resistant and effectively earthquake resistant.
