000010312 520__ $$2eng$$aA negative stiffness is regarded as one of the promising control strategies in view of absolute response reduction except that such a control requires, in general, active or semi-active devices. In order to attain the negative stiffness more economically, a new structural control device that realizes a negative stiffness in a passive manner is proposed. The developed device is a typical slide bearing, except that the inverted convex curve is introduced on the sliding plate to generate the negative stiffness. The prototype of the proposed device was assembled, and its performance was investigated by the shaking table test using a girder model with rubber bearings. It was confirmed thorough series of tests that the proposed device generated stable and desired negative stiffness that reduced maximum inertia force of the girder significantly compared to the ordinal friction bearings without considerably increasing the absolute and relative displacement.
