Development of Autonomous Negative Stiffness Damper for Reducing Absolute Responses

Last updated on 21 April 2016 3:20

In this paper, a new vibration control device realizing negative stiffness in a passive manner is proposed in order to reduce the absolute response of structures under strong seismic motions. The developed device consists of a sliding plate with a PTFE portion, and they are vertically pressurized by coil springs.
