Collisions between a moving mass and an anti-collision device increase structural responses and threaten structural safety. An active mass damper (AMD) with stroke limitations is often used to avoid collisions. However, a strokelimited AMD control system with a fixed limited area shortens the available AMD stroke and leads to significant control power. To solve this problem, the design approach with variable gain and limited area (VGLA) is proposed in this study. First, the boundary of variable-limited areas is calculated based on the real-time status of the moving mass. The variable gain (VG) expression at the variable limited area is deduced by considering the saturation of AMD stroke. Then, numerical simulations of a stroke-limited AMD control system with VGLA are conducted on a high-rise building structure. These numerical simulations show that the proposed approach has superior strokelimitation performance compared with a stroke-limited AMD control system with a fixed limited area. Finally, the proposed approach is validated through experiments on a four-story steel frame.

To improve the seismic responses of the traditional floating floor structure (FFS), an inerter-enhanced FFS, namely the In-FFS, was recently proposed by the authors. The multifold improvements offered by the In-FFS compared to the FFS have been investigated based on the seismic responses analysis. In this work, the superior performances of the In-FFS are investigated and demonstrated based on the energy analysis method. It is found that, thanks to the dynamic equivalent mass effect of the inerter, the input energy of the entire system under seismic inputs is suppressed. Compared with the conventional frame structure (FS), the maximum mechanical energy of the primary structure is reduced by around 75% and 80% for the FFS and In-FFS, respectively. As a result, dynamic responses of
