"The purpose of this study was to develop a practical bearing arrangement scheme for continuous steel-plate-girder highway bridges in infrequent seismic zones such as the Central and Eastern United States. The bearing arrangement should be suitable to accommodate seismic forces while it allows for free thermal expansion. Metallic dampers are used to provide longitudinal fixity for the bridge’s superstructure. The scope of this study includes optimizing the shape of metallic dampers through experimental verification so that the dampers can dissipate maximum energy during earthquakes, experimentally studying the cyclic behavior of full scale metallic dampers, and investigating the dynamic behaviors of dampers installed in a small-scale bridge system. The end result of this study is to develop a practical design procedure for metallic dampers in bridge applications.
Past research conducted in the area of metallic plate dampers was reviewed and is discussed. The data obtained from the experimental study was analyzed and evaluated to determine how the damper acts as an isolator and an energy dissipater in bridge applications. From this study it can be concluded that the dampers are effective for the dissipation of energy during an earthquake event and that they can be used to isolate the ground motion from propagating into the superstructure"--Abstract, page iii.
