The present work investigates the effectiveness of Magnetorheological Damper (MR) damper coupled with the smart self-powered system, MR damper acts as electromagnetic induction (EMI) device in controlling seismic vibration. The proposed smart damping system with an EMI device is capable of converting vibration energy into electrical energy. Thus, the EMI device attached with MR damper can be used as an effective and alternative power source for the MR damper, making it a self-powering system. The primary aim of the experimental study is to identify the performance of the proposed smart damping system using time history loading (El Centro earthquake). For experimentation, the MR damper with EMI was designed and fabricated. To reduce sedimentation, nano Fe3O4 was used in the preparation of MR fluid. The performances of the proposed smart damping system are compared with the passive, semi-active and active control system in force and displacement to evaluate the effectiveness of the self-powered smart damping system in reducing seismic vibration. The experimental results show that the self-powered smart damping system produces more damping force and reduction in displacement. The maximum damping force obtained is 0.67 kN. In an active system, a force was increased by 12.9% and displacement was reduced by 13.4% when compared with the semi-active control system. The results revealed that the proposed EMI can act as a sole power source for the damping system.
