Ductile end diaphragms have been suggested as an appropriate device in the past to improve the seismic response of steel girder bridges. This paper investigates the efficiency of the seis-mic design strategy that utilized a slab-connected steel plate as a ductile diaphragm in the superstructure. Protecting the main girder from typically reported damage and mitigating the transferred lateral load to the non-ductile substructures are the main objectives of this study. The results show that a slab-connected thin steel plate with low yielding stress (LYS) can miti-gate the force demand on the non-ductile substructures and act as a structural fuse. It can also reduce the transverse displacement of the superstructure and, consequently, prevent the end of the main girder from buckling and/or yielding.
