A long-term dense monitoring system of seismically isolated tall building in Tokyo Institute of Technology is introduced. Recently, the number of monitoring reports of seismically isolated building is gradually increasing. In this monitoring system, the acceleration at the ground surface, 1st, 2nd, 7th, 14th, and 20th floor is recorded in detail, as well as the story drift and acceleration at the floor where the base isolators are located. Using the data, it is expected that the propriety of the current seismic design be verified.
