摘要

Possible to prevent the occurrence of excessive stress in the present invention relates structures for extended seismic isolation period of the base-isolated structure, thereby increasing the damping effect of the base-isolated structure with friction damping, it is also possible to grant Triggering by static friction, configured to provide a base-isolated structure and rigidity devices simple negative. Tilt mechanism with the sliding or rolling of the horizontal slide [SOLUTION] or rolling element (14), and an inclination enables the sliding surface of the sliding element rolling surfaces of the body (12) or rolling (11 negative stiffness device comprising a) (10). It is possible to the rollers or wheels (14b), and rolling elements, and a lower member or the upper member either. Tilting mechanism (11) is a laminate planar Utatedo-ban (12), configure and output (13) an elastic pad made of an elastic material, laminated and flat rolling plate and a thin steel plate and the elastic member I can be configured in the. Configure the base-isolated structure stiffness devices and the negative (10), and a device having a restoring force characteristics, it is possible to use a negative stiffness, you can easily return to origin.
