The maximum seismic response of irregular U-turn curved bridge is significantly related to the pier and deck connection. An irregular U-turn curved bridge with radius of 45m, 8.5m total width and 154m total length was analyzed in this paper. This highly horizontally curved bridge was evaluated by performing nonlinear time history analysis on the representative bridge model with 3 types of connection between pier and deck: (i) rigid connection, (ii) hinge connection, and (iii) lead rubber bearing connection. Nonlinear hinge was modelled at the base and the top of the pier by using fiber hinge. Moreover, the effect of the number of connection between pier and deck was evaluated. The results indicate that bridges with one connection give better performance level than those with two connections; however, bridges with only one connection is more critical to the torsion issue.
