Abstract

An innovative seismic retrofit strategy to improve earthquake resistance of steel bridges has been developed. The strategy involves the use of ductile steel bridge end-diaphragms which have been calibrated to yield before the strength of the substructure is reached. Based on analytical studies, the proposed ductile diaphragms exhibit an appropriate ultimate seismic behavior, and the impact of the intermediate diaphragms on seismic performance of the slab-on-girder bridges is minimal. Laboratory testing demonstrate their large initial elastic stiffness, high strength and capacity to dissipate hysteretic energy.
