To predict the earthquake damage, we have constructed database of the super high-rise buildings in Osaka prefecture and identified the fundamental period of 32 super high-rise buildings by micro-tremor measurements. More than 20% of the super high-rise buildings are base-isolated, and more than 80% of the base-isolated buildings are condominium. The largest proportion of the building use was office before 2000. However, the construction of condominium has increased since 2001. After the 1995 Hyogo-ken Nambu earthquake the fundamental natural period has been short in Osaka. The fundamental natural period was about 1.1 to 1.3 times to that at the completion.
