Abstract
From past to present, the seismic resistant design have changed whenever the architectural and civil structures sustained serious damage due to unexpected earthquakes. The bridge design has changed greatly for the cause of the Great Hanshin Earthquake and the seismic resistant design of general girder bridges has made great progress. On the other hand, as the middle or large span bridges such as arch bridge and truss bridge have complicated behavior, it is difficult that the design method of girder bridge apply to these type bridges. The authors have developed the hysteresis brace (Damper Brace) as the energy-dissipating device and verified the elasto-plastic characteristics of Damper Brace by quasi-static and dynamic shaking table tests. The development of this Damper Brace enabled the rational design of the arch bridge.
