Abstract: This report offers the proceedings of the First U.S.-Japan Workshop on Earthquake Protective Systems for Bridges, held in Buffalo, New York on September 4 and 5, 1991. This comprehensive workshop saw the presentation and discussion of 41 papers covering a wide range of topics: seismic isolation hardware, the testing of isolated bridges and components, active control and hybrid systems, design issues and applications, long span bridges, seismic retrofit and new construction. Of particular interest was the difference in philosophy between menshin design in Japan and seismic isolation as practiced in the United States. The need to lengthen the period of vibration is not so important (in Japan) as the requirement to keep joint clearances small. Other issues included joint design, displacement restraint devices, and durability of isolation hardware in the field. This report also contains a set of resolutions adopted at the meeting regarding future cooperation between the United States and Japan.
