Optimal design and performance assessment of multiple tuned mass damper inerters to mitigate seismic pounding of adjacent buildings

This work investigates the efficiency of tuned inerter dampers (TIDs) in controlling seismic response two adjacent buildings and pounding distance between them. Pervious research on this subject has shown that installing TIDs every floor one coupling each with additional inerters (CS1) provides best control performance. Some potential drawbacks solution are large number devices used practical difficulties associated sharing buildings. To overcome these drawbacks, we propose a new configuration TMDIs, called here as CS2. The proposed makes use much fewer than CS1 does not require Contrary to findings published literature, show uncoupled systems can be configured more effective coupled systems. superior performance system is primarily due different arrangement CS2 compared CS1. In CS2, connected TMD masses rather floors done Performance assessment its comparison carried out through numerical examples several ground motions covering range amplitude frequency content. first example, heights but similar fundamental periods vibration. second one, same height vibrations. These cover cases facing lower higher risk pounding, respectively. found better existing TID both studied here.
