Segmented upper stories of the structure are isolated as a tuned mass, and a passive viscous damper or semi-active resetable device is adopted for energy dissipation. Optimum TMD control parameters and appropriate matching resetable TMD (RTMD) configurations are adopted from a previous study on a simplified two degree of freedom (2-DOF) system. Log-normal statistical performance results are presented for 30 probabilistically scaled earthquake records. The time history analysis and normalized reduction factor results show the response reductions for all seismic hazards. Thus, large semi-active isolated stories building systems can effectively manage seismic response for multi degree of freedom (MDOF) systems across a broad range of ground motions in comparison to passive solutions. This research demonstrates the validity of the isolated stories building systems using RTMD control strategy for consideration in future design and construction.
