Sponsoring Agency Code Study conducted in cooperation with the U. S. Department of Transportation, Federal Highway Administration Research Study Title: "Analysis of Curved Steel Girder Units" 16. Abstract The design of mu1tigirder bridge units with horizontal curvature is complicated by the torsional forces induced by the curvature. The proportioning of girders for preliminary design requires an approximate analysis that accounts for the curvature. This report presents the development and an evaluation of an approximate analysis procedure for curved girder bridges. The V-load method is named because the effects of curvature are represented by self-equilibrating vertical loads acting on the girders. The V-load method, as implemented in the analysis procedure described in this report, is suitable for approximate analysis of preliminary bridge designs. The analysis procedure includes composite behavior, and allows variable radius of curvature and skew supports. Envelopes of bending moment and shear force due to moving track loads can be generated. The V-load method is evaluated by comparing the approximate response with the response from a more refined finite element analysis for a variety of bridge configurations. 17.
