Title: Seismic behaviour of an isolated bridge with directional effects

Abstract: The directional effects plays an important role in the seismic design of bridge structure. Most of the past studies on the bridges have been conducted by ignoring the directional effects. However, such effects can play crucial role in the seismic response of the bridge. In the present paper, the seismic response of a continuous bridge under bi-directional excitation has been studied, considering the interaction effects in Bearings and piers. The effect of orientation of the major component of ground motion with respect to the axis of the bridge has also been studied. A comparison of the responses obtained from the Nonlinear (Static) Pushover analysis and Nonlinear Dynamic Time History analysis have also been done. It has been observed that the bi-directional excitation has resulted in significantly higher response with the maximum effect in case of PF system, where the uni-directional analysis yield significantly underestimated results, which might be crucial in seismic design. © 2009 ASCE.
