In this paper, a story isolation system is modeled by a simple two degree of freedom model for theoretical study on the control mechanism of a story isolation system. A procedure to optimally design the isolator parameters of a story isolation system is put forward, based on the minimum base shear variance. The control mechanism of the story isolation system is systematically investigated for various location of isolation layer. Results demonstrate that the working mechanism of the story isolation system is changed from tuning frequency, isolation and energy dissipation to base isolation when the isolation layer is moved from roof to the bottom of the structure, corresponding to three zones: base isolation zone, mid-story isolation zone and tuning frequency zone. There exist an optimal damping level for the isolation layer in the tuning frequency zone and the base isolation zone. However, a higher damping level of the isolation layer results in a better performance in the mid-story isolation zone.
