The vibration control structure with steel dampers to absorb the seismic force has mainly prevailed in high-rise building. Near future, it will be
expected to prevail in low and middle-rise building. Several studies have been made on the vibration control system in high-rise building. These show
that the effect of response reduction is different from the arrangement of damper. Another example, damper is not worked effectively by bending
deformation on upper part of building. But there has been a few studies tried to the vibration control system in low and middle-rise building.
In this paper, we change the damper arrangement and installation and consider the effect by response comparison. In addition, we evaluate the
prediction method which can catch tendency of effective damper deformation. It would be helpful to know the optimum arrangement and installation in
low and middle-rise building.
