| Research Abstract |
Dynamic behaviors and seismic safety of a viaduct in an urban area are investigated through experimental and analytical approaches by focusing onmutual interactions and individual dynamic behaviors of some functional devices andmembers for seismic proof and for seismic isolation at the girder ends. It is concludedthat the mutual interactions among the functional devices and members stronglyinfluence on dynamic behaviors of the isolated viaduct and new bridge isolationapproaches effectively work when considering spatial constraints of existing and/ornew bridge structures.
