Abstract
A stiffness method for the analysis of simply supported curved girder bridges with horizontal sector plates and vertical cylindrical shell elements is outlined. Stiffness coefficients of sector plates are presented herein whereas stiffness coefficients of shell elements are based on Hoff's solution of Donnell's equations. A numerical example illustrating the application of the method is shown. Some interesting results, particularly those with respect to the effect of radius of curvature, were obtained. A comparison is made between the results of a curved twin box girder bridge obtained by the proposed method and Tung's method.
