| Summary: | Curved bridges have become a major component of highway systems in recent years. Elevated freeways and multi-Level interchange structures are very common in densely populated areas and could hardly be constructed without curved bridges. Usually, these bridges are of cellular cross section so that the high torsional moments due to curvature can be resisted economically. Methods of analysis and design to date have been very approximate, but because of the large number of curved bridges being constructed everywhere, refined methods of analysis are desirable. In this thesis, the main geometric parameters of curved bridges are studied. The finite strip method of analysis applied to folded plate structures as a box girder, for which a general computer program was written. This method of analysis is restricted to structures simply supported alone their straight radial edges. Finally, on the basis, of this refined analytical method, the behavior of curved box girder bridges is studied. In particular, wheel load distribution characteristics are investigated especially with respect to the load position of the bridges. |
