Abstract
The Hanshin/Awaji Earthquake caused extensive damage to many bridge of the Hanshin Expressway. Especially falling-down of superstructures and other destructive damage occurred at Benten Kouku which locates b downtown of Kobe. After the earthquake, the continuous 19-span space frame bridge with lead rubber bearings which has approximate 565m bridge length was reconstructed in this region. It is the first trial in Japan to use large lead rubber bearings as an isolator or as a damper at the bottom of the steel pier for the purpose of reduction of seismic force acting on this bridge. Therefore this study had vibration tests via a jack. This paper describes the results of vibration tests and make a comparison between experiment and analysis.
