Abstract

The role of cultural heritage is immeasurably important in human lives and societies. However, invaluable treasures have been damaged or lost due to natural disasters such as earthquakes. This paper studied fundamental properties of Japanese traditional wooden structure: Kiyomizu temple in Kyoto which is famous for its high stage structure. First, aging change of the building was investigated using measurement of moisture content. All the columns had no severe aging change, and the moisture content was less than 20%. Then, the micro tremor was measured to evaluate the natural frequency and damping factor. The results showed the fundamental natural frequency was 1.8Hz and the damping factor was 7%.
