Abstract

According to past researches, partial retrofitting which install steel dampers into lower stories of existing high-rise building as vibration control method for long-period ground motion is suggested. This paper reports the seismic response and response characteristics of the analysis models partial installed oil dampers or steel dampers aimed at enhancing the adaptive range of partial retrofitting. The analysis result shows effectiveness of oil damper and some points of attention to design such as the increase of deformation in the damper installed stories and the damper non-installed stories.
