| Research Abstract |
In order to contribute to efficient seismic upgrading or seismic retrofit for steel bridges whose dynamic behavior is complex (such as arch and truss bridges), a series of extensive studies have been performed on developing steel or aluminum alloy high-performance seismic dampers that would not loose their functions even for major earthquakes three times. Furthermore, damage reducing effects due to installing high-performance seismic dampers in arch or truss bridges are demonstrated experimentally and analytically.
