In this study the performance of two box girder bridges under near-field earthquakes was investigated. Lateral responses of two continuous span bridges were compared under two cases: with lead rubber bearings (LRB) and with rigid connections between the superstructure and substructure. Lead rubber bearings are one of the most popular seismic isolators which are used in a variety of structures such as buildings and bridges. Fifteen isolators were installed under the deck of the isolated bridge. It was observed that the superstructure received less acceleration when the bridge was equipped with lead rubber bearing isolators. There was a significant difference between the isolated and non-isolated structures in terms of base shear force and the isolated bridge showed better performance under near-filed earthquakes. This suitable performance of the isolated structure was due to the proper hysteric behavior of the lead rubber bearings.
