Earthquake Resistant Verification of a 5-Span Steel Box Girder Bridge

The earthquake resistant design for roadway bridges introduced in 1992 is conducted according to the "Standard Specification for Roadway Bridges", Division V, Seismic Design and the first revision of the Standard was done in 1996. However, dur to different concepts of the earthquake resistant design from those of the other designs, the provisions given in the Standard are still not applied appropriately. In this paper the verification of the earthquake resistant capacity of a bridge with typical configurations, 5-span steel box girder bridge, is carried out based on the application rules of the present Standard in order to provide clear understandings about the earthquake resistant verification and the earthquake resistant design as well.n as well.
