Optimization of Seismic Response of Steel Structure using Negative Stiffness Damper

Earthquakes of greater magnitude can cause severe destruction. One important tool to minimize the destruction is seismic protection of structures. Many strategies have been developed for it and one important strategy is introducing negative stiffness in the structure. Negative stiffness damper (NSD) introduces true negative stiffness in the structure. The NSD gives force in the direction of the displacement and hence it is called Negative Stiffness. The present study focuses on modelling NSD device in a commercial software tool (ETABS 2016) and implementing the device on 3D Steel frames to control seismic parameters like base shear, Storey displacement and Top storey acceleration. Keywords - Negative stiffness damper, Seismic response control.
