Summary:Environmental vibration problem was occurred at the house nearby the highway bridge on the soft ground. The vibration tests using test vehicle were carried out in order to investigate the cause and the characteristics of the bridge and the house vibration. As the results of the examination, it is clear that the house, which lives in complainer, resonated with the bridge. Then the keel dampers were installed at the ends of girders as the vibration countermeasure. This study evaluated the validity of the countermeasure due to running ordinary trucks. However it is necessary to compare the measured data of before and after countermeasure by the unified vibration tests. Therefore the effect of vibration reduction was examined by the dynamic response analysis due to running vehicles.
