- Long-term microtremor monitoring in a Base-Isolated Steel Reinforced Concrete plus Steel Complex Structure
この論文をさがす
抄録
A continuous microtremor monitoring was conducted for nine months inside the Kyushu University Hospital South Building in order to observe variation of its natural frequencies with changes of temperature and wind velocity. The subjected building was completed in 2001 and is a base isolated 13-story high structure with Steel-Reinforced Concrete (SRC) frames up to 5 stories and Steel frames on top of it. Three microtremor measurement devices were installed to the top floor, the basement floor and the isolator pit level, and were scheduled to measure every two hours for a five minutes measurement since February 2007 up to now, December 2007. Also the temperature at the isolator pit level and at the roof level as well as the wind velocity were measured. Spectral ratios from microtremor data were calculated and their pealcs were picked up. It was observed that the predominant frequency of the upper structure increases when the temperature increases. Contrary to this the predominant frequency of the isolated layer decreases when temperature increases.
