  Preamble

It is a main opportunity for me to work for the Structural Design Lab. As a foreign student, my research work gives me the possibility to learn by different ways and adapt my-self to new situations. I am feeling lucky, not only for studying at Seoul National University but also for living in South Korea and discovering its culture every day.

Objectives

Estimation of the damping of the Second Jindo Bridge (South Korea)

Methodology

Analysis methods as Random Decrement method or Eigensystem Realization Algorithm use field measurement data given by a sensor network settled on the Second Jindo Bridge. These methods estimate modal parameters. This study focuses on the calculation of the damping ratio for the first vertical frequency of the bridge.

Expected Results
The comparison between damping ratios of the First and the Second Jindo Bridges is expected to explain vibrations on the second bridge. A slight difference between damping ratios in the range 0-1% could show a large displacement at the center of the deck.

Progression

First results after analysis with Matlab programs are not satisfactory. Studying methods and improving programs are under way.
