Abstract:
Many steel tower structures built in Japan are aging and are increasingly at risk of collapse in the event of typhoons or major earthquakes. At the same time, it is difficult to proceed with rebuilding such aging structures with limited budgets and manpower, thus there is a need to monitor the health of the structures, and to equalize and facilitate the rebuilding work. For this purpose, it is necessary to make full use of sensing technology to diagnose deterioration in order to accurately assess the condition of steel tower structures. In this study, sensors were installed at multiple locations on an actual steel tower structure, and measurements were taken over a period of nine months. Data was measured and saved for five minutes, centered on the time when the maximum RMS value of acceleration occurred each day. There have been no other studies in which measurements were taken and analyzed at the time when the maximum vibration occurred each day, with almost no missing data, over several months of constant measurement. This study aims to obtain knowledge that will be useful for monitoring the health of structures and for leveling and smoothing out reconstruction work in order to prevent loss of life due to the collapse of steel tower structures that have not yet been made apparent.
