| Abstract: |
This paper describes the dynamics characteristics of an old steel truss bridge. The bridge, known as Yurikyo was constructed in the sixth year of the Showa era (1931) and become a symbol of Honjo city and of the Yuri region in Akita Prefecture, Japan. The bridge spans 175.6 m over the Koyoshi river been formed by three identical single trusses of 57.6 m. Due to aged and corrosion of steel elements, replacements of this old bridge by new reinforced concrete one was planned during the year 2005 and construction is planned to be started in 2009. In this research, the old steel bridge is investigated by means of micro vibration measurements, Fourier analysis and finite element method to estimate the dynamics properties of the bridge and to obtain the basic data that could be a reference for future structural monitoring of the new bridge. |
