Pre-Eccentric Distances Design of Curved Continuous Girder Bridges with Single-Column Supports

According to the shortcomings in the pre-eccentric distance design of curved continuous girder bridges with single-column supports,a curved continuous girder bridge of varies radius with single-column supports is analyzed by FEM.Appropriate pre-eccentric supports distances for the curved continuous girder bridges with varies radius are studied in this paper.Not only the torque distribute of curved girder is taken into account in the design of curved continuous girder bridges with single-column supports,but also the rotation angles displacement of main girder and the reaction of main girder end bearing should be considered.The important factors which are taken into account in the design of curved continuous girder bridges with single-column supports are not same for varies radius.
