Abstract
In Osaka, the 40-story high-rise building with visco-elastic dampers was constructed in 1999. The structural frame of this building consists of steel girders and concrete filled steel tubular columns. Earthquake observation has been performed since the building completion. Many records have been observed. Then we made the earthquake response analysis was made using the three dimension frame model with the visco-elastic dampers which considered temperature and frequency dependency, and good correlations were obtained between the earthquake observation records and the analysis results. The vibration reduction effect of the damper was confirmed by comparing the analysis results of the model with dampers and the model with no damper. By comparing the analysis results of the condition that the temperature is quite different, it was confirmed that the vibration reduction effect of the damper has the difference.
