The authors have developed a passive variable friction damper (VFD) which produces a decreased frictional force when its displacement exceeds a predetermined value. The purpose of this study is to evaluate the response flexural deformation control effects of steel super high-rise buildings using VFDs subjected to strong earthquakes. In the present paper, dynamic response analyses and static pushover analyses were conducted using thirty-story frame structure models with VFDs or conventional friction dampers (FDs). The result indicated that VFDs can mitigate flexural deformations compared with FDs in whole building and damper-installed span by 4-7% and 8-32%, respectively.
