abstract

Negative stiffness systems have been widely studied for their seismic response reduction characteristics and have been found to be very effective in reducing seismic responses in structures. Based primarily on the concept of introducing flexibility in the structure, they bring about seismic response reduction by reversing the force–deformation behaviour of the structure-device assembly. While some negative stiffness devices alter the physical behaviour of the structure to deformation, some devices show “pseudo negative stiffness” behaviour by means of a control algorithm. To have the best possible reduction of seismic response in structures, it is essential that an optimal combination of dampers is used. The present work studies the performance of true negative system (TNS) and an adaptive negative stiffness system (ANSS) on a 5 degree of freedom shear structure. The optimal values of parameters and optimal number of dampers are studied based on the response such as inter-storey drifts, accelerations, displacements and base shear obtained from MATLAB analysis.
