Design of Curved I-Girder Bridges
In recent years there has been an ever-increasing demand for curved girder bridge systems. This has created a need for reliable methods by which such systems may be designed and analyzed. Methods developed to date do not adequately account for the effects of both girder warping and the interaction of adjacent girders due to radial diaphragm action. For bridge systems subjected to dead load with no composite action, significant error in the calculation warping stress (flange bending) may result. The objective of this report was to develop a method of analysis for curved girder bridge systems and to develop a set of design aids for dead load. Also included are design guides for live load effects (static and impact), which were developed during a previous study. The design aids are limited to single span bare steel (DL) and composite curved structures (LL). (Modified author abstract)
