Concrete Box-girder Bridges

From a detailed research and development programme, information relevant to mostphases of the design process for concrete box-girder bridges has been derived. First, a synthesis of past designs has enabled certain features to be identified, related to the geometry of the structure and likely bounds placed upon them, thus facilitating the initial selection and proportioning of the structure. Secondly, relevant methods of analysis have been surveyed and recommendations made on their suitability in different'circumstances for treating the serviceability conditions iri the structure. Associated with this is a parameter study to highlight the significance of warping stresses and transverse flexural stresses in relation to the longitudinal flexural stresses. Finally, the treatment of the ultimate strength of these structures is discussed. B.I. Maisel, R.E. Rowe and R.A. Swann
