Conventional seismic resisting structural systems may be subjected to permanent deformation and damage through strong earthquakes, which can induce considerable post-earthquake repair costs. This paper presents an easy and fast way to reduce link plastic rotation demand, residual link plastic rotation, maximum absolute floor acceleration repair costs, time and also a system for seismic retrofitting of the eccentrically braced frames (EBFs): a self-centering inverted Y-braced EBF system that combines shape memory alloy bars and lead rubber damper (SMA-LRD). Four and nine-story steel frames are designed and analyzed with and without the proposed system to quantify their seismic performance using the OpenSees. Over 5000 nonlinear time history analyses were conducted to evaluate the seismic performance of proposed hybrid device using 28 ground motion records. The results of incremental dynamic analyses (IDA) show that implementing the new system leads to a considerable reduction in maximum drifts, residual drifts, and residual displacements.
