The forced vibration tests and earthquake observations were performed to confirm the vibration characteristics of the high-rise building with high damping oil dampers. This paper first reports the outline and structural design concept of the building, and then presents the performances of the oil damper. Next, the damping ratio for the first mode added by oil dampers is evaluated through the forced vibration tests. Then, the outline of earthquake observations and the identification of the first natural period are presented. Finally, a simulation analysis model is constructed on the same concept in the structural design. It consists of an oil damper model and a building frame model based on the test results and observations. The validity of the simulation analysis method of the building with oil dampers is verified through the simulation analyses.
