The main goal of this study is to investigate the effectiveness of backward-shared tuned mass damper inerter (BSTMDI) in reducing inter-storey drift as well as pounding between adjacent buildings. A backward-shared-TMDI (BSTMDI) linking two adjacent medium-rise buildings is presented, considering the practical and economical part of design parameters. Inerter in BSTMDI can generate higher reaction forces based on the large relative acceleration response between the two adjacent buildings, which efficiently enhance the seismic performance of both buildings. Moreover, a benchmark structure consisting of two adjacent medium-rise buildings equipped with (BSTMDI) is examined. Eight design parameters of the BSTMDI are optimized through single-objective optimization problems using a genetic algorithm (GA) to minimize either the inter-storey drift or the pounding gap distance of the two adjacent benchmark structures. Mitigating effects of the optimally designed (BSTMDI) on the responses of the benchmark structures are assessed considering a set of one hundred (100) natural ground motions records. It is found that the BSTMDI scheme can reduce the inter-storey drift and pounding distance responses similarly or even better than a single shared tuned mass damper inerter (SSTMDI) using a smaller inertance ratio. The same trend is observed while using backward-shared tuned inerter damper (BSTID) compared to a single shared tuned inerter damper (SSTID). Both BSTMDI and BSTID have proven their robustness under a large set of natural real earthquake records with various frequency characteristics for several dynamical parameters such as displacement, inter-storey drift, pounding gap and stroke displacement.
