Departmental Bulletin Paper 鋼桁橋の耐震設計法の変遷と制震技術

頭井, 洋

This paper describes the evolution and the current situation of the seismic design method and the seismic control technologies about the road steel girder bridges. The transition of the seismic code is outlined and the seismic control technologies of the steel bridges are introduced centering on the damping devices used for the steel girder bridges. In addition, the estimating methods are explained for the maximum displacement of bridges during large earthquakes.
