Many observation records are recorded by the seismometer installed in the buildings during the 2011 off the Pacific coast of Tohoku earthquake. These observation records are analyzed, and the variability of the eigen period and the equivalent damping factor is considered much. In this paper, the results of the documents are integrated and reanalysis is carried out separately for each type of structure, building height, input level of earthquake ground motion. In addition, it's investigated about setting of an analysis model in high building evaluation from 1966.2 to 1998.12.
