Abstract

This paper reports the results of vibration and meteorological observations of a buildng built on Hashima, Nagasaki, southern part of Japan, which was registered as a World Heritage Site in 2015 [1], and analyzes its dynamic characteristics. Hashima is called "Battleship Island" because its appearance resembles a battleship due to the many buildings standing upon it. The structure contributing most to the battleship appearance is No. 3 Building. An accelerometer and a weather sensor have been installed in No. 3 Building for long-term measurements. Multi-modal analysis of vibration and meteorological data was performed for 5 months, and the dynamic characteristics of No. 3 Building were examined.
