In this paper, eight noded iso-parametric curved quadratic shell elements are used for Finite Element formulation to analyze continuous bridge deck curved in plan. The computer program developed based on the formulation presented in this study has been used to evaluate the influence of different parameters such as curvature and aspect ratio on the behavior of continuous curved bridges subjected to uniformly distributed load. Though a curved bridge problem is very regular in structural engineering, a detailed and rigorous analysis is often advised since the introduction of curvature brings complexity in structural response. The parametric study carried out in this investigation to establish the defined relationship between the structural behavior of curved bridge deck and straight bridge would prove to be very useful for bridge engineers to readily assess the behavior of continuous bridge curved in plan, based on the responses for a straight bridge deck without compromising on the accuracy.
