Mid and high rise buildings having a natural period of about one second suffer inevitable damage under severe earthquake ground motion, although dampers are installed. This study is to clear up the effect of frame plasticity to seismic response deformation on passively vibration-controlled buildings. Based on the equivalent linearization technique, it is shown that response deformation is increased by frame plasticity but increment is few and the relationship between amount of dampers and main-frame damage can be estimated quantitatively.
