This paper presents the highlights of several studies on seismic performance of bridges. The results showed that superelastic shape memory alloys, fiber reinforced grouts, built-in elastomeric pads, concrete-filled fiber-reinforced polymer (FRP) columns,and FRP-wrapped segmental columns successfully resisted earthquake forces while substantially reducing apparent damage In addition,the seismic performance of innovative connections developed for prefabricated bridge columns was satisfactory and comparable with that of the conventionalearthquake-resistant RC bridge columns while the implementation of such details decreased the construction effort considerably
